Marshall, C.J.
This case arises out of a property dispute [490]*490between R. Christian Haufler and Thomas and Nancy Zotos (collectively, Zotos),3 who own land adjacent to each other along the North River in Marshfield (town). At issue is whether an escrow agreement between Haufler and Zotos concerning transfer of title of a triangular portion of Haufler’s land to Zotos is enforceable, and whether delivery of the deed effectively conveyed title to Zotos. Haufler claims that ownership of the triangular parcel is essential to his plans to construct a new house on his property under the town’s applicable zoning bylaws,4 and that the terms of the escrow agreement, executed by Zotos some fifteen months after Haufler had signed it, did not reflect their agreement. Also at issue is whether Zotos violated the Massachusetts Civil Rights Act (act), G. L. c. 12, §§ 11H-11I,5 by interfering through “threats, intimidation or [491]*491coercion” with Haufler’s right to use and enjoy his property.
After a trial before a judge in the Superior Court, the judge ruled that the escrow agreement was enforceable, delivery of the deed was effective to convey title, and Zotos did not violate the act.6 We affirm the judge’s order with respect to the escrow agreement and validity of the deed. We vacate his order with respect to the civil rights claim.
1. Procedural background. In October, 1999, Haufler commenced an action in the Land Court against Zotos challenging the validity of a deed transferring title of a triangular portion of land he owned in Marshfield to Zotos. Haufler also claimed that Zotos interfered with his constitutional right to use and enjoy his property by threatening to “oppose construction on any portion” of his land, and by recording the deed to the triangular parcel “in order to defeat [Haufler’s] ability to construct the proposed residences,” in violation of the act. Haufler subsequently moved for a preliminary injunction to enjoin Zotos’s “continuing trespasses” on his property, which was allowed by a judge in the Land Court in November, 1999.
On Zotos’s motion, the case was transferred to the Superior Court in October, 2000, pursuant to G. L. c. 211B, § 9. Some two years later, in September, 2002, Haufler filed a complaint for contempt, alleging that Thomas Zotos had violated the preliminary injunction entered in the Land Court.7 In January, [492]*4922003, a judge in the Superior Court held a two-day trial on the contempt complaint, vacated the preliminary injunction issued by the Land Court, and issued a new preliminary injunction.8 In March, 2003, the same judge held a bench trial on Haufler’s remaining claims. In a comprehensive memorandum and order, the judge concluded that the escrow agreement was enforceable against Haufler and that the deed to the triangular parcel had been properly recorded by Zotos; he entered a declaratory judgment to that effect, stating that Haufler “does not own or have any legal right, title or interest in the triangular parcel.” The judge further concluded that Haufler’s claim under the act failed because the collective conduct of the defendants did not constitute “threats, intimidation or coercion” within the meaning of the act. Haufler appealed,9 and we granted his application for direct appellate review.
2. Factual background. We summarize the facts as found by the judge, supplemented by undisputed facts from the record. In May, 1995, Haufler purchased a 6.7-acre L-shaped parcel of land on Littles Lane in Marshfield (Lot C) from Ralph and Kathleen Campanelli (collectively Campanelli), and in September, 1995, Campanelli transferred to Haufler a building permit they had previously obtained for the lot. Lot C is heavily wooded and is bordered on the north by the North River and [493]*493conservation land administered by the National Audubon Society. At the time of Haufler’s purchase, no house had been built on Lot C, but there were two buildings on the lot, a “cottage” and a “garage.”10 The cottage is situated on a small triangular parcel that extends from the eastern border of Lot C into the adjacent lot, Lot D. The judge found that Haufler planned to obtain a new residential building permit for Lot C on the theory that the cottage located on the triangular parcel constituted a preexisting residential structure that would entitle him to such a permit. Haufler planned to obtain the permit, pour his foundation, and then demolish the cottage.11 Once this was accomplished, Haufler was prepared to convey the triangular parcel to the owner of Lot D.
At some point Haufler, Campanelli, and the then-owner of Lot D, Aldro French, entered into an agreement (Campanelli agreement) concerning the triangular portion of Lot C.12 Haufler (identified as “the buyer”) agreed that “upon obtaining a building permit to build which shall be applied for immediately,” he would “remove the existing cottage and shed within seventy-five (75) days of purchase” and would convey to French “the triangular piece of property on which the [cottage] and [shed] presently exist.” The stated purpose of the Campanelli agreement was “to continue the easterly sideline of the premises to be sold [by French] in a straight line.”
Thereafter, on January 29, 1996, French executed a purchase and sale agreement with Zotos for the purchase of Lot D-l.13 The premises described in the French-Zotos purchase and sale [494]*494agreement included the “triangular shaped parcel of land,” although at the time Haufler had not conveyed title of that parcel to French as contemplated by the Campanelli agreement. Zotos retained an attorney, Steven Graham, to represent them at the closing, which was set for May 15, 1996.
As the closing date approached, Haufler still had not conveyed the triangular parcel to French. Because Zotos did not wish to rescind the purchase and sale agreement with French, they authorized Graham, as the judge found, “to make appropriate binding agreements on their behalf to obtain title to the triangle consistently with their purchase and sale agreement.” Graham thereupon obtained for Zotos an assignment of French’s rights under the Campanelli agreement. In anticipation of the French-Zotos closing, in early May, 1996, Graham telephoned Haufler to negotiate an agreement to the effect that Haufler would execute the deed to the triangular parcel, and Graham would hold the deed in escrow for Zotos. He then sent a letter to Haufler “to confirm the agreement” reached during the telephone conversation. The letter stated that Graham required from Haufler (in time for the closing still scheduled for May 15, 1996) a plan of the triangular parcel suitable for recording; a deed to the parcel; and a mortgage on the lot to be recorded at the time of closing “for the full performance of all undertakings in the agreement listed below.” The letter further stated that Graham would prepare and send to Haufler for his signature: (1) an “agreement to convey the [triangular] property upon the start of construction on [Haufler’s] property and to move the [cottage] currently located on the property to my client’s property”; and (2) an agreement “to [ejscrow the amount of $5,000 to cover the expenses of moving the [cottage14] onto my Ghent’s property.”
Graham then prepared and sent to Haufler an escrow agreement dated May 14, 1996, to be executed by Haufler and Zotos, [495]*495which, the judge found, Graham drafted to accommodate the interests of both parties “consistently with his discussions” with Haufler.15 The escrow agreement began with a series of recitals concerning the rights of Zotos to the triangular parcel under the purchase and sale agreement with French, and Haufler’s need for the triangular parcel to accomplish his building permit objectives. The agreement then provided that Haufler would execute a deed to Zotos for the triangular parcel to be held in escrow by Graham and not recorded “until the occurrence of the events described in paragraphs 2 or 3, whichever occurs the earliest.” Paragraph 2, in turn, stated that Zotos would record the deed on “the commencement of construction on the dwelling” on Haufler’s land.16 Paragraph 3 stated that Zotos “shall be entitled to record the deed . . . on or after August 30, 1996, notwithstanding the failure of Haufler to commence construction prior to that time.”17 Haufler signed the agreement, which had not yet been signed by Zotos, and had his signature notarized on May 14, 1996. The following day he sent the signed escrow agreement to Graham together with $5,000, the mortgage, and two signed and notarized deeds18 for the triangular parcel of Lot C.19 The closing occurred, Zotos [496]*496obtained title to Lot D-l, but as we describe below, Zotos did not sign the escrow agreement until some fifteen months later.
Haufier encountered unanticipated delays because of his plans to subdivide Lot C, which in turn stalled commencement of any construction on his land. According to the town’s zoning code enforcement officer, by subdividing Lot C into Lots “C-l” and “C-2,”20 Lot C-l was essentially rendered “nonconforming” because it did not have sufficient frontage on Littles Lane. For this reason, on July 10, 1996, the town rescinded the original (Campanelli) building permit for Lot C.21
By August 30, 1996, the date provided in the escrow agreement, Haufier had not obtained a new building permit, much less started construction of his house. The date passed without Zotos pressing the matter, and Haufier continued to pursue his plans to subdivide Lot C and to build a house on each subdivided lot. In April, 1997, while his appeal from the town’s rescission of the original building permit for Lot C was pending, see note 21, supra, Haufier applied for new building permits for Lots C-l and C-2, respectively. He also installed a well and had septic plans drawn up for each parcel.
It was during this period that Zotos began actively to oppose Haufier’s building plans. Zotos came to believe that the original issuance of a building permit for Lot C had not been legal because the cottage on the triangular parcel had not been occupied and was therefore not a preexisting residential structure. Zotos’s opposition to Haufier’s plans for building two new houses on his property increased when the town indicated that this might require paving Littles Lane. During the spring or summer of 1997, Haufier’s building permit applications for [497]*497Lots C-l and C-2 were denied, and Haufler appealed to the town’s zoning board of appeals (board). As an abutter, Zotos was notified of the public hearing on Haufler’s applications, scheduled for September, 1997.
In August, 1997, nearly one year after August 30, 1996, the date contained in the escrow agreement, Zotos signed the escrow agreement, and Graham, after some hesitation, gave Zotos the deed to the triangular portion of Lot C. Unbeknownst to Haufler the deed was recorded by Zotos on August 18, 1997. The following month at a hearing before the board on Haufler’s building permit applications for Lots C-l and C-2, Nancy Zotos informed the board that Haufler no longer owned the triangular parcel. Because he then had no basis for obtaining his building permits, Haufler withdrew his applications.
3. Enforceability of the escrow agreement. The judge concluded that the delivery by Haufler to Graham of the signed escrow agreement, two deeds to the triangular parcel, the mortgage, and the sum of $5,000 “amounted to acceptance” by Haufler of Zotos’s “offer as expressed in the written contract.” Accordingly, he ruled that the escrow agreement was enforceable against Haufler, and the deed conveyed title to Zotos.
On appeal, Haufler disputes the enforceability of the escrow agreement for three reasons. First, Haufler contends that express authority was required for Graham to bind Zotos in contract, see See v. Norris, 234 Mass. 345, 348-349 (1920), and that Graham was not so authorized.22 See Rossi v. School Comm. of Everett, 354 Mass. 461, 464 (1968). The argument fails. Author[498]*498ity is “the power of the agent to affect the legal relations of the principal by acts done in accordance with the principal’s manifestations of consent to him.” Restatement (Second) of Agency § 7 (1958). See Restatement (Third) of Agency § 2.01 (Tent. Draft No. 2) (“An agent acts with actual authority when, at the time of taking action that has legal consequences for the principal, the agent reasonably believes, in accordance with the principal’s manifestations to the agent, that the principal wishes the agent so to act”). See also Theos & Sons v. Mack Trucks, Inc., 431 Mass. 736, 743-744 & n.13 (2000) (discussing express and implied authority). There is ample evidence in the record to support the judge’s finding that Zotos gave Graham the authority to “make appropriate binding agreements on their behalf to obtain title to the triangle.”23 See Restatement (Second) of Agency, supra at § 12 comment a, at 57 (exercise of agent’s power to alter legal relations between principal and third persons “may result in binding the principal to a third person in contract”). Certainly his finding is not clearly erroneous.
Next, Haufler argues that the escrow agreement was not enforceable because Zotos did not manifest his acceptance of the agreement by signing it within a reasonable time.24 A written contract, signed by only one party, may be binding and enforceable even without the other party’s signature if the other [499]*499party manifests acceptance. See Putnam Mach. Co. v. Mustakangas, 236 Mass. 376, 378 (1920) (although only defendant signed contract, plaintiff could still recover for breach where plaintiff “assented to and accepted” contract). See also 2 S. Williston, Contracts § 6:43, at 467-469 (4th ed. 1991) (“any written contract, though signed by only one party, will bind the other if he accepts the writing”). Cf. Bartlett v. Boston, 182 Mass. 460, 462-463 (1903) (defendant city bound by terms of deed where there was evidence of acceptance of deed by city, although city commissioners who drew up and signed deed were not agents of city). The escrow agreement by its terms did not require Zotos’s signature to be effective. Moreover, Graham assented to the escrow agreement on behalf of Zotos by holding the deeds, mortgage, and sum of $5,000 in escrow until the deadline specified in the escrow agreement had passed. See Kaarela v. Birkhead, 33 Mass. App. Ct. 410, 412-413 (1992) (in absence of formal escrow agreement, letters between attorneys established terms of escrow agreement, and escrow agent’s deposit of funds constituted acceptance of terms recited in correspondence). By not recording the deed until one year after August 30, 1996, Zotos performed within the terms of the agreement. The judge was correct to conclude that the “absence of signatures by [Thomas and Nancy Zotos] did not prevent the formation of the contract.”
Finally, Haufler claims that his execution of the escrow agreement was an offer, not an acceptance. Haufler points to his trial testimony concerning a conversation he had with Graham after he had sent Graham the executed escrow agreement to the effect that they agreed the deed would not be recorded until Haufler had poured the foundation for a new house. This, he claims, amounted to a withdrawal of his original offer (the executed escrow agreement), which could no longer be accepted by Graham on behalf of Zotos.25 This argument is also unavailing.
An offer is a “manifestation of willingness to enter into a [500]*500bargain,” Restatement (Second) of Contracts § 24 (1981), and is often a “conditional promise dependent for its enforceability on the offeree giving in exchange the offeror’s requested act,” 1 S. Williston, Contracts § 4:4, at 266 (4th ed. 1991). On behalf of Zotos, Graham initiated discussions with Haufler and proposed the terms of an escrow agreement. As consideration, Zotos offered more time for Haufler to obtain a building permit in exchange for his executing a deed and placing it in escrow.26 The delivery of the signed escrow agreement, together with two signed and notarized deeds, a mortgage on his property, and the sum of $5,000 to Graham belies any argument that Haufler was making an offer rather than accepting an offer. The judge correctly concluded that Haufler’s performance of the conditions that conformed to the terms of the written escrow agreement “was convincing evidence” of Haufler’s acceptance of the agreement as written.
Haufler has maintained throughout the litigation that the escrow agreement he signed was but a draft, the terms of which had not been fully determined. See Rosenfield v. United States Trust Co., 290 Mass. 210, 216 (1935) (failure to agree on material terms may be evidence that parties do not intend to be presently bound). He and Graham “never” discussed “any time [501]*501requirements,” he said, and the August 30, 1996, date contained in the escrow agreement was not a negotiated term: it would have been “impossible” for him to start construction on his house by August 30, 1996, he argues, because of the building permit appeals process.
Haufler also testified, however, that he did not “really” read all of the provisions of the escrow agreement, but “scannjed] the agreement” before signing it and sending it back to Graham. Haufler may well have overlooked the August 30, 1996, date, but that provides him with no legal comfort. “The general rule is, that, in the absence of fraud, one who signs a written agreement is bound by its terms whether he reads and understands it or not.” Wilkisius v. Sheehan, 258 Mass. 240, 243 (1927). The inclusion of the August 30, 1996, date in the escrow agreement may have differed from Graham’s May 9 letter to Haufler. But as the judge noted, Haufler is “an attorney of considerable experience and skill.” Had he intended to reject the term providing for an August 30, 1996, cutoff date, “he would not have signed the written contract without making a written modification on the contract itself.” The judge was correct to conclude that the escrow agreement was binding and enforceable.
Our conclusion to this effect disposes of Haufler’s claims that, if the escrow agreement is not enforceable, delivery of the deed to Zotos was ineffective to convey title. We now turn to Haufler’s civil rights claim.
4. Civil rights claim. We first describe the facts that form the basis of Haufler’s claim under the act. At varying times after they recorded the deed, Zotos, as the judge found, engaged in a “long train of complaints and objections” about Haufler and other neighbors, including letters to local, State, and Federal officials, some of which, in the judge’s words, “raised legitimate issues under applicable zoning laws” and “[mjany” of which were “frivolous or of little merit.”27 Several of Zotos’s letters were general complaints about land use and development on Littles Lane and did not target Haufler in particular.
[502]*502In addition, the judge found that Thomas Zotos “engaged in abusive conduct” toward Haufler while Haufler was on his own property. The judge also found that Thomas Zotos “intentionally followed and harassed” a neighbor more than once while the neighbor was waiting with his young children on Haufler’s property. On one occasion Thomas Zotos pulled next to the neighbor in his car in what the neighbor described as “a threatening manner.” On another, when Haufler arrived at his property, a sawhorse was blocking the dirt road on his land.28 The driver of his automobile moved the sawhorse, whereupon Thomas Zotos “came running up the hill at the car and yelling” in what Haufler described as a “very aggressive” manner. When Haufler noted that he owned the property, Thomas Zotos responded that he did not care and that he was going to contact the police.
The judge also found that Thomas Zotos harassed individuals hired by Haufler to work on his land. In two separate incidents, Thomas Zotos “verbally insulted and harassed” a worker and later telephoned a police officer, falsely accusing the worker of trespassing on Haufler’s land.29 The judge also found that Thomas Zotos “verbally harassed and abused” a surveyor hired by Haufler to plot boundary lines and locate the stumps of cut trees. Thomas Zotos’s abusive behavior continued even when the surveyor returned with a uniformed town police officer. At that point, Thomas Zotos called the surveyor and the officer “perverts,” jumped up and down, wrongfully claimed they were on Zotos’s property, and ordered them off the property shouting epithets and profanities.30
Haufler hired a real estate appraiser to document Zotos’s encroachments on Haufler’s property. As the appraiser approached Haufler’s property, Thomas Zotos ran toward him with a rake, holding it “like present arms style ... up in the [503]*503air.” The appraiser described Thomas Zotos as “very belligerent, very aggressive.” The appraiser returned later with a town police officer. Thomas Zotos confronted the appraiser and the police officer and was, in the appraiser’s words, “extremely aggravated, very insulting, and . . . talking at the top of his voice.” All of these incidents resulted in the workers Haufler had hired leaving the property without completing the work they had been hired to perform.
The judge further found that Thomas Zotos trespassed on Haufler’s land when he removed lot line markers placed by the surveyor hired by Haufler. Thomas Zotos also placed “no trespassing” signs and birdhouses on trees on or near Haufler’s property line. The judge found the birdhouses contained electronic equipment that “may have been surveillance or video equipment.” He also found that Thomas Zotos had placed “[njails and boards with nails in them” on the dirt road on Haufler’s land.31 Finally, the judge found that Zotos “unlawfully cut trees on [Haufler’s] property near their common boundary in the area approaching the river front.” Haufler claims, contrary to the judge’s ruling, that all of this behavior, in addition to Zotos’s recording of the deed, violated his civil rights under the act.
First, he argues that the judge “incorrectly interpreted the act by focusing his analysis on the conduct of the defendant that was directed solely at [Haufler].” The judge should, he says, have considered not only Zotos’s actions directed at Haufler, but also Zotos’s behavior toward third parties. Contrary to Haufler’s claim, it is not at all clear that the judge concluded otherwise.32 Threatening, intimidating, or coercive actions directed at third parties should be included in considering any [504]*504conduct that forms the basis of a claim under the civil rights act. Cf. Redgrave v. Boston Symphony Orchestra, Inc., 399 Mass. 93, 100 (1987) (no exemption for civil rights deprivations resulting from third-party pressure under the act); Sarvis v. Boston Safe Deposit & Trust Co., 47 Mass. App. Ct. 86, 92 (1999) (in context of coercion, actual or potential physical confrontation “may involve third persons” and “threat of harm need not be directed at the plaintiff”). See also Bell v. Mazza, 394 Mass. 176, 180 (1985) (threat to plaintiffs’ contractor considered part of allegations supporting civil rights claim).
To evaluate Haufler’s claim we therefore consider Zotos’s entire conduct, separating it for ease of reference into three categories: (1) the recording of the deed to the triangular parcel allegedly in order to prevent Haufler from constructing a house on his property; (2) Zotos’s repeated complaints to local, State, and Federal officials about Haufler’s use of his land; and (3) Zotos’s repeated trespasses on Haufler’s land and harassment of Haufler, his neighbors, and workers whom Haufler hired to work on his property. We conclude that the recording of the deed and Zotos’s complaints to various officials did not violate the act, but that the aggregate conduct described in the third category did.
To establish a claim under the act, Haufler “must prove that (1) his exercise or enjoyment of rights secured by the Constitution or laws of either the United States or of the Commonwealth, (2) has been interfered with, or attempted to be interfered with, and (3) that the interference or attempted interference was by ‘threats, intimidation or coercion.’ ” Bally v. Northeastern Univ., 403 Mass. 713, 717 (1989). Haufler easily establishes the first prong: the right to use and enjoy one’s own property is constitutionally secured. See Brett v. Building Comm’r of Brookline, 250 Mass. 73, 77 (1924).
As to the second and third prongs, the Legislature enacted the civil rights act to provide “enhanced protection of civil rights” under State law at a time when “[deprivations of secured rights by private individuals using violence or threats of violence were prevalent . . . .” Batchelder v. Allied Stores Corp., 393 Mass. 819, 821 (1985). We have recognized that the act was not intended to create a “vast constitutional tort,” Bell [505]*505v. Mazza, supra at 182, and that the remedies under the act were “explicitly limited” to those situations “where the derogation of secured rights occurs by threats, intimidation or coercion.” Bally v. Northeastern Univ., supra at 718, citing Bell v. Mazza, supra at 182-183. Nonetheless, the act is “entitled to liberal construction of its terms.” Buster v. George W. Moore, Inc., 438 Mass. 635, 645 (2003), quoting Batchelder v. Allied Stores Corp., supra at 822. See Batchelder v. Allied Stores Corp., supra, quoting 2A C. Sands, Sutherland Statutory Construction § 54.04, at 570 (4th ed. 1984) (“cases within the reason, though not within the letter, of a statute shall be embraced by its provisions”).
We use a reasonable person standard to determine whether Zotos’s conduct constituted threats, intimidation, or coercion under the act. See Planned Parenthood League of Mass., Inc. v. Blake, 417 Mass. 467, 474-475, cert. denied, 513 U.S. 868 (1994) . In the context of the act, a “threat” consists of “the intentional exertion of pressure to make another fearful or apprehensive of injury or harm.” Id. at 474. “Intimidation” involves “putting in fear for the purpose of compelling or deterring conduct.” Id. “Coercion” is “the application to another of such force, either physical or moral, as to constrain him to do against his will something he would not otherwise have done.” Buster v. George W. Moore, Inc., supra at 646, quoting Planned Parenthood League of Mass,, Inc. v. Blake, supra. See also Freeman v. Planning Bd. of W. Boylston, 419 Mass. 548, 565 (1995) , quoting Webster’s New Third Int’l Dictionary 439 (1981) (defining “[cjoercion” under the act as “the use of physical or moral force to compel [another] to act or assent”). We clarified recently that the scope of coercion under the act is not limited to actual or attempted physical force. See Buster v. George W. Moore, Inc., supra at 646-648 (emphasizing “moral” force as a possible form of coercion, and holding that economic coercion standing alone, in certain circumstances, may be actionable under the act).
Applying those principles here, the thrust of Haufler’s claim with respect to the deed is that Zotos’s recording of the deed was calculated to impede Haufler’s plans for constructing a house on his property. This is an allegation of a deprivation of [506]*506rights that is not coercive “because it is not an attempt to force someone to do something that person is not lawfully required to do.” Freeman v. Planning Bd. of W. Boylston, supra. See Swanset Dev. Corp. v. Taunton, 423 Mass. 390, 396 (1996) (“To the extent that the plaintiffs allege that various delays were a deliberate attempt to frustrate their development plans, they have alleged a direct deprivation of rights rather than an attempt at coercion”). Zotos did not deprive Haufler of his right to build a house on his property; he was lawfully entitled to record the deed. Cf. Buster v. George W. Moore, Inc., supra at 648 (no economic coercion where defendants “lawfully entitled to foreclose” on plaintiffs’ property). The town’s zoning bylaws may prevent Haufler’s development of his land; Zotos has not done so.
As to Zotos’s “long train of complaints and objections” to various officials, the judge was correct to conclude that these did not represent threats, intimidation, or coercion within the meaning of the act. Words reasonably understood to express an intention to use lawful means to block development “would not be a threat, intimidation, or coercion actionable under § 11I.” Pheasant Ridge Assocs. Ltd. Partnership v. Burlington, 399 Mass. 771, 782 (1987). See Sena v. Commonwealth, 417 Mass. 250, 263 (1994) (“a threat to use lawful means to reach an intended result is not actionable under § 111”); Bell v. Mazza, supra at 183 (“allegations which merely indicate that a defendant petitioned for the redress of grievances, absent extraordinary circumstances, are not sufficient to state a claim under G. L. c. 12, § 11I”). The judge’s finding that only some of Zotos’s letters “raised legitimate issues under applicable zoning laws” and that “[mjany” of them were “frivolous or of little merit” is tempered by the fact that most of the letters concerned general complaints about land use and development on Littles Lane and did not target Haufler in particular.33
Zotos’s other conduct stands on different footing. A reason[507]*507able person could have felt threatened or intimidated by some of the conduct of Thomas Zotos. Several of Haufler’s workers and Haufler’s neighbor testified that the defendant’s behavior was “threatening” or that they felt “threatened” by him. Haufler and another worker described Zotos’s behavior as “very aggressive.” Thomas Zotos ran at one worker with a rake in hand, and threatened to telephone the police when the saw horse was moved from the dirt road so Haufler could drive across his own property. Even the presence of a police officer did not deter Thomas Zotos, who showed no intention of retreating from any confrontation and, on two separate occasions, forced a worker accompanied by a police officer off Haufler’s property, shouting epithets. Zotos also telephoned the police to have an authorized worker removed for trespassing.34
The conduct here is similar, if not more egregious, than the conduct at issue in Bell v. Mazza, 394 Mass. 176, 183-184 (1985), where we held that the plaintiffs’ allegations were sufficient to withstand the defendants’ motion to dismiss, and Ayasli v. Armstrong, 56 Mass. App. Ct. 740, 753 (2002), where the Appeals Court held that the defendants’ conduct violated the act. In Bell v. Mazza, supra at 179-180, the plaintiffs alleged that the defendants, in opposition to the plaintiffs’ plans to construct a tennis court on their property, threatened to do anything at any cost to prevent the construction of the tennis court, formed an association of neighbors to that end, threatened to sue the plaintiffs’ contractor, attempted to induce the electric company to discontinue electric service to the plaintiffs, physically blocked a plaintiff’s passage onto the land, responded to her greeting with epithets, and contacted the police and fire departments several times concerning the construction on the plaintiffs’ property. In Ayasli v. Armstrong, supra at 743-746, in addition to opposing the plaintiffs’ development plans before [508]*508town boards, the defendants told the contractor working on the plaintiffs’ house that they had a video camera and would be keeping track of the project, went onto the plaintiffs’ property to take photographs, and had gates erected across the plaintiffs’ deeded right of way over the defendants’ land, forcing the plaintiffs to use an impassable route to access their property. In that case, the defendants’ conduct “constitut[ed] persistent efforts to disturb the plaintiffs’ enjoyment of their land, to impede access, limit use, and generally make [the plaintiffs] so uncomfortable . . . that they would abandon their plans for the house.” Id. at 753. The same can be said of Zotos’s conduct here.
The conduct on which we focus occurred after the recording of the deed, which was the key factor in thwarting Haufler’s development plans. But the conduct did interfere with Haufler’s right to use and enjoy his property. Haufler testified that he did not “drive down there much,” had “avoided” going to his property in the latter part of 2002, and was “afraid” to go to his property. Zotos’s abusive conduct also interfered with Haufler’s ability to have workers (a surveyor, for example) come to his property. Zotos’s conduct was persistent and antagonistic. Cf. Rattigan v. Wile, 445 Mass. 850, 852-853, 856-861 (2006) (in residential property dispute, unpleasant odors, sounds, and visual conditions on defendant’s property were substantial and unreasonable interference with neighboring plaintiff’s use and enjoyment of property and therefore constituted nuisance). Their behavior escalated beyond a property dispute into threatening belligerence and unprovoked hostility. On balance, and in light of our earlier discussion, we conclude that Zotos did violate the act.
We now turn to the question of remedy. In his complaint and on appeal, Haufler sought damages for the violation of his civil rights. Under the act, Haufler is entitled to injunctive relief and compensatory damages. See note 5, supra. A comprehensive permanent injunction addressed to the conduct that constitutes violations of the act has already issued.35 We therefore remand [509]*509the case to the Superior Court for a determination of the appropriate amount of compensatory damages.
So ordered.
