Robie, J.
*90*1109Defendant Daniel Jason Thomas appeals his convictions for possession of a dirk or dagger, possession of methamphetamine with prior convictions, and possession of drug paraphernalia. On appeal, he contends it was error to deny his motion to suppress under Penal Code1 section 1538.5 as *1110the detention and patsearch were not justified by reasonable suspicion. We agree and reverse the judgment.2
FACTUAL AND PROCEDURAL BACKGROUND
Based on the evidence discovered during the search of defendant, he was charged with carrying a concealed dirk or dagger, felony possession of methamphetamine based on a prior strike conviction, and misdemeanor possession of a smoking device.3 The information also alleged a prior strike conviction.
After the preliminary examination, defendant filed a motion to suppress under section 1538.5. Following an evidentiary hearing, the magistrate denied the motion.
Suppression Hearing
In April 2016 at 12:23 p.m., the Sacramento Police Department received a call that a "male black adult subject wearing a dark hoody, ... and black pants" was harassing customers in front of a business in the Del Paso Heights area. The description of the subject was clarified as a gray hooded sweatshirt and black pants. Additional information included that the subject had "set up camp," "there was some kind of homeless camp set up nearby," and defendant "appeared to have something mental going on," in that he did not seem to understand when people were speaking to him. There was no information in the call regarding threats, trespassing, battery, physical assault, or weapons being involved.
The Del Paso Heights area has a high crime rate. There are a high number of transients and homeless people in the area. There is also a "fair amount" of foot traffic in the area due to the retail shops and restaurants.
Officer Mark Kimble and his beat partner responded to the area at 2:54 p.m., approximately two hours and 20 minutes after the initial call. Defendant was wearing "bulky clothing, bulky hooded sweatshirt and bulky pants, as well as a windbreaker jacket on top of that." Kimble indicated it was a "pretty warm ... afternoon." He was seated on the sidewalk approximately 70 to 80 yards away from the complaining business. There was no one else in the immediate vicinity.
*91*1111The officers contacted defendant "and he repeatedly would not give his name on multiple different requests." The officers explained why they were in the area and speaking to defendant, but he "repeatedly would not give his name." Based on "what he was wearing, the totality of the circumstances," Kimble asked defendant if he had any weapons on him. Defendant said he was not on probation, did not have to speak to the officers, and began walking away. Burnett put defendant in a control hold, Kimble handcuffed him and performed a patsearch for weapons. In the course of that search, Kimble felt an item that felt like a fixed blade knife and what felt like a narcotics pipe. After removing the knife from the lining of defendant's jacket, Burnett "observed" a BET card at the bottom of defendant's pant leg, near his left boot, with defendant's name on it. Kimble performed a records check and it showed defendant was on informal searchable probation. The officers continued to search defendant and found methamphetamine in the same pocket the pipe had been in.
The parties stipulated the scope of the suppression hearing was limited, as defendant was only contesting the initial detention and Terry4 patsearch.
Defendant argued that generalized harassment is not a crime; thus, officers responding to a general call of harassment, are not responding to a report of a crime. In addition, there was more than a two-hour time lapse between the call and the officer's contact with defendant, the description given was vague and general, the area was heavily trafficked, and there were a great number of transients in the area. Thus, the officers did not have a reasonable suspicion that a crime had been committed. Moreover, counsel argued, defendant was not aggressive or threatening and did not appear under the influence of a controlled substance. He noted California does not have an identification law requiring compliance with a law enforcement officer's request to identify oneself. Defense counsel argued, therefore, there was no basis to justify a Terry search. Defense counsel acknowledged it was reasonable for the officers to make a consensual contact with defendant, but when they restrained and detained him, "they went a step too far."
The People argued that the 911 call, coupled with defendant's attire, behavior, lying, refusing to identify himself, and starting to walk away gave the officers reasonable suspicion. The People also argued discovery of the knife and drug paraphernalia was inevitable, because if defendant had "been forthcoming with his identity from the beginning, the officers would have learned of [his] probation condition sooner and would have inevitably searched [him] and discovered the evidence."
*1112The magistrate, Alan G. Perkins, found there was sufficient suspicion to contact defendant, as he was in physical proximity to the location two and one-half hours after the call, in daylight. Given the minor "nature of the crime," the magistrate reasoned defendant would not have felt compelled to get away from the scene quickly. The magistrate also found there was sufficient basis to presume the conduct complained of was sufficient to be "some kind of criminal offense or some kind of conduct that might lead to danger to others or perhaps even to the person doing the harassing." The magistrate then found "the combination of the crime being harassing conduct, the person being in the area, the *92homeless camp nearby, the lack of cooperation which by itself is not a crime but combined with other factors and the factor that the defendant was dressed in at least what might seemingly be overdressed for the occasion in the sense it was a very hot day with bulky sweatpants and a wind breaker, I think would barely but sufficiently give the officer suspicion that there might well be something concealed under there that could be a danger." Accordingly, the magistrate denied the motion to suppress.
Trial
After the denial of the motion to suppress, the matter proceeded to jury trial. A jury found defendant guilty of all three charges. In bifurcated proceedings, the trial court found the prior conviction allegation true. The trial court sentenced defendant to a term of two years on possessing a dirk or dagger, doubled pursuant to the strike, a concurrent two-year term on felony possession of methamphetamine, doubled pursuant to the strike, and time served on the misdemeanor possession of drug paraphernalia, for an aggregate term of four years in prison.
DISCUSSION
Defendant contends it was error to deny his motion to suppress. He contends the investigative detention and patsearch were not justified by reasonable suspicion, as the report was stale, overly general in its physical description of him, and vague in its assertion of any criminal activity. The People argue defendant is estopped from arguing the search was unlawful because he lied to the officers when he told them he was not on probation when he was, and in any event, there was reasonable suspicion to support the stop and patsearch search.
The Fourth Amendment protects against unreasonable searches and seizures. ( U.S. Const., 4th Amend.; Terry v. Ohio , supra , 392 U.S. at p. 20, 88 S.Ct. at p. 1879, 20 L.Ed.2d at p. 905.) "A seizure of the person occurs ' "whenever a police officer 'by means of physical force or show of authority' restrains the liberty *1113of a person to walk away." ' " ( People v. Douglas (2015) 240 Cal.App.4th 855, 860, 193 Cal.Rptr.3d 79, quoting People v. Celis (2004) 33 Cal.4th 667, 673, 16 Cal.Rptr.3d 85, 93 P.3d 1027 ; see People v. Brown (2015) 61 Cal.4th 968, 976-977, 190 Cal.Rptr.3d 583, 353 P.3d 305.) Warrantless searches and seizures are presumed to be unreasonable, " 'subject only to a few specifically established and well-delineated exceptions.' " ( People v. Diaz (2011) 51 Cal.4th 84, 90, 119 Cal.Rptr.3d 105, 244 P.3d 501.) "There are two different bases for detaining an individual short of having probable cause to arrest: (1) reasonable suspicion to believe the individual is involved in criminal activity [citation]; and (2) advance knowledge that the individual is on searchable probation or parole." ( Douglas , at p. 860, 193 Cal.Rptr.3d 79 ; see People v. Schmitz (2012) 55 Cal.4th 909, 916, 149 Cal.Rptr.3d 640, 288 P.3d 1259.) "[A] search founded on neither reasonable suspicion of criminal activity nor advance knowledge of a probation search condition can aptly be characterized as arbitrary." ( In re Jaime P. (2006) 40 Cal.4th 128, 138, 51 Cal.Rptr.3d 430, 146 P.3d 965 ; see People v. Hoeninghaus (2004) 120 Cal.App.4th 1180, 1188, 16 Cal.Rptr.3d 258.) In reviewing a trial court's ruling on a motion to suppress, we defer to the trial court's express or implied *93factual findings if supported by substantial evidence. ( People v. Redd (2010) 48 Cal.4th 691, 719, 108 Cal.Rptr.3d 192, 229 P.3d 101 ; People v. Woods (1999) 21 Cal.4th 668, 673-674, 88 Cal.Rptr.2d 88, 981 P.2d 1019.) "However, if the undisputed facts establish that the search or seizure was constitutionally unreasonable as a matter of law," we are not bound by the trial court's ruling. ( People v. Middleton (2005) 131 Cal.App.4th 732, 738, 31 Cal.Rptr.3d 813 quoting People v. Medina (1972) 26 Cal.App.3d 809, 815, 103 Cal.Rptr. 337.) We independently determine whether the facts found amount to a reasonable search or seizure under the Fourth Amendment. ( Redd , at p. 719, 108 Cal.Rptr.3d 192, 229 P.3d 101 ; Woods , at pp. 673-674, 88 Cal.Rptr.2d 88, 981 P.2d 1019.)
The People claim defendant cannot challenge the validity of the "search and seizure as a probation search" because he was on informal searchable probation and lied when he told officers he was not on probation. In making this claim, they rely on our decision in People v. Watkins (2009) 170 Cal.App.4th 1403, 89 Cal.Rptr.3d 135. In Watkins , we held that a defendant who intentionally misrepresented his identity to prevent law officers from discovering his probation or parole status and search conditions was equitably estopped from challenging the search as a probation search. ( Id. at pp. 1408-1409, 89 Cal.Rptr.3d 135.)
The People are raising this claim for the first time on appeal.5 "[F]or a suppression ruling to be reviewable, the underlying objection, contention or *1114theory must have been urged and determined in the trial court." ( People v. Manning (1973) 33 Cal.App.3d 586, 600, 109 Cal.Rptr. 531.) "[T]he scope of issues upon review must be limited to those raised during argument, whether that argument has been oral or in writing. This is an elemental matter of fairness in giving each of the parties an opportunity adequately to litigate the facts and inferences relating to the adverse party's contentions." ( Manning , at p. 601, 109 Cal.Rptr. 531.) It was the People's burden to raise the issue of equitable estoppel at the suppression hearing. ( People v. Williams (1999) 20 Cal.4th 119, 136, 83 Cal.Rptr.2d 275, 973 P.2d 52 [At the suppression hearing, once defendant has made the prima facie showing that the police acted without a warrant, the prosecution "has the burden of proving some justification for the warrantless search or seizure, after which, defendants can respond by pointing out any inadequacies in that justification"]; LaRue v. Swoap (1975) 51 Cal.App.3d 543, 551, 124 Cal.Rptr. 329 ["The burden of pleading facts which raises the issue of estoppel lies with the party who would estop the other party [citation], and for estoppel to be available it must be specially pleaded"].) "Failure to plead estoppel constitutes a waiver and we need not consider the issue for the first time on appeal." ( Ibid. ) Because the People did not raise and argue the issue of equitable estoppel, *94defendant was not permitted to litigate the issue, and the trial court was not required to rule on it. Accordingly, the claim of equitable estoppel is forfeited on appeal.
When a defendant challenges the legality of a warrantless search or seizure, the People must establish that the search fell within one of the recognized exceptions to the warrant requirement. ( People v. Romeo (2015) 240 Cal.App.4th 931, 939, 193 Cal.Rptr.3d 96 ; People v. Hoeninghaus , supra , 120 Cal.App.4th at p. 1184, 16 Cal.Rptr.3d 258.) "A probation search is one of those exceptions. ( People v. Schmitz [, supra ,] 55 Cal.4th ... [at p.] 916 [149 Cal.Rptr.3d 640, 288 P.3d 1259]...; People v. Woods [, supra ,] 21 Cal.4th ... [at pp.] 674-675 [88 Cal.Rptr.2d 88, 981 P.2d 1019]... [probation exception based on advance consent].)" ( Romeo , at pp. 939, 193 Cal.Rptr.3d 96 ; see Hoeninghaus , at p. 1184, 16 Cal.Rptr.3d 258.)
There are, however, limitations on the applicability of the probation exception. As relevant here, "the exception is inapplicable if police are unaware of the probation search condition at the time of a warrantless search." ( People v. Hoeninghaus , supra , 120 Cal.App.4th at pp. 1184, 1194-1195, 16 Cal.Rptr.3d 258 ; also In re Jaime P. , supra , 40 Cal.4th 128, 51 Cal.Rptr.3d 430, 146 P.3d 965 ; People v. Sanders (2003) 31 Cal.4th 318, 332-333, 2 Cal.Rptr.3d 630, 73 P.3d 496 ; People v. Robles (2000) 23 Cal.4th 789, 797, 97 Cal.Rptr.2d 914, 3 P.3d 311 ;
*1115People v. Durant (2012) 205 Cal.App.4th 57, 64, 140 Cal.Rptr.3d 103 ; Myers v. Superior Court (2004) 124 Cal.App.4th 1247, 1252, 22 Cal.Rptr.3d 369.)
In this case, the record is clear, the officers were unaware defendant was on searchable informal probation until after they placed him in a control hold, handcuffed him, and conducted a patsearch for weapons. Because the officers were unaware of the probation search condition at the time they detained and searched defendant, they cannot rely on the existence of this probation condition to now justify the search and seizure.
"[T]o justify an investigative stop or detention the circumstances known or apparent to the officer must include specific and articulable facts causing him to suspect that (1) some activity relating to crime has taken place or is occurring or about to occur, and (2) the person he intends to stop or detain is involved in that activity." ( In re Tony C. (1978) 21 Cal.3d 888, 893, 148 Cal.Rptr. 366, 582 P.2d 957 ; People v. Souza (1994) 9 Cal.4th 224, 231, 36 Cal.Rptr.2d 569, 885 P.2d 982 ; Terry v. Ohio , supra , 392 U.S. at p. 30, 88 S.Ct. p. 1884-1885, 20 L.Ed.2d at p. 911.) "The corollary to this rule, of course, is that an investigative stop or detention predicated on mere curiosity, rumor, or hunch is unlawful, even though the officer may be acting in complete good faith." ( In re Tony C. , at p. 839, 148 Cal.Rptr. 366, 582 P.2d 957.) It remains the prosecution's burden to prove "that the warrantless search or seizure was reasonable under the circumstances." ( People v. Williams , supra , 20 Cal.4th at p. 130, 83 Cal.Rptr.2d 275, 973 P.2d 52.)
Here, the facts are undisputed. In the middle of the day, a person contacted law enforcement officers to report an adult black male wearing a sweatshirt and dark pants was "harassing" customers. The subject appeared to have some mental health problems and had "set up camp." The area was a high-crime area, with a high number of transients and homeless people. The area also has a "fair amount" of foot traffic *95due to numerous retail shops and restaurants. Two and one-half hours after they received the call, law enforcement officers arrived to the area. They saw defendant sitting on the sidewalk, approximately 80 yards away from the business. He was wearing a Windbreaker, sweatshirt, and dark pants. There was no one else in the area.
A vague description does not provide reasonable suspicion to stop every person falling within that vague description. ( In re Carlos M. (1990) 220 Cal.App.3d 372, 381-382, 269 Cal.Rptr. 447.) A more detailed description, including such characteristics as age, hair or eye color, attire, height and build combined with additional suspicious circumstances, might reasonably justify a detention. ( People v. Fields (1984) 159 Cal.App.3d 555, 564, 205 Cal.Rptr. 888 [detention lawful where the defendant matched victim's description of suspect's race, gender, height, general age, and attire]; People v. Harris (1975) 15 Cal.3d 384, 387, 124 Cal.Rptr. 536, 540 P.2d 632 ["male Caucasian, dark *1116hair, moustache, about 5 feet 8 inches tall, about 150 pounds, wearing a light cardigan sweater and dark trousers"]; People v. Flores (1974) 12 Cal.3d 85, 89, 115 Cal.Rptr. 225, 524 P.2d 353 ["Mexican-Americans, wearing dark clothing and wide-brimmed hats, each being 5 feet 8 inches to 5 feet 9 inches tall, and weighing 160 to 165 pounds" and driving a dark-colored General Motors "fastback" sedan of mid-1940's vintage].) Here, the caller provided an extremely vague and very general physical description of the person "harassing" customers. The description did not include any reference to the person's height, weight, or age. Even the clothing was nondescript, a sweatshirt and black pants. There was nothing distinguishing in the description of the person or his clothing. The most potentially distinctive information provided was that the subject appeared to have mental health problems, did not understand what people were saying, and had "set up camp." There was no indication in the record defendant displayed any behavior suggesting a mental health problem or lack of understanding when the officers approached and spoke with him. Nor was there any indication he had "set up camp." Such a vague description does not provide reasonable grounds to stop every person falling within that vague description. ( In re Tony C. , supra , 21 Cal.3d at p. 898, 148 Cal.Rptr. 366, 582 P.2d 957 ; In re Carlos M. , supra , 220 Cal.App.3d at pp. 381-382, 269 Cal.Rptr. 447.)
A general description combined with a close temporal and geographical connection between the crime and the suspects, may justify a detention. ( People v. Conway (1994) 25 Cal.App.4th 385, 390, 30 Cal.Rptr.2d 533 [detention lawful where stop occurred within two minutes of receiving report of a burglary]; People v. Lazanis (1989) 209 Cal.App.3d 49, 54, 257 Cal.Rptr. 180 [detention lawful stop occurred within moments of burglary report]; People v. McCluskey (1981) 125 Cal.App.3d 220, 223, 178 Cal.Rptr. 7 [lawful detention description included height, race, facial hair, approximate age and general clothing, stop conducted within five minutes of report of robbery].) Here, although there was geographic proximity to the business, the officers were at the scene two and one-half hours after the call was made. In addition, this was not a secluded or remote area. It was a business area, with significant foot traffic, in the middle of the day.
*96Two and one-half hours in a busy area is a significant lapse of time, and that lapse of time combined with the general physical description did not provide reasonable suspicion.
In addition, in the authorities cited above, an actual crime was reported-the threshold requirement in a Terry stop. Those reports of crimes gave rise to an indication that "some activity relating to crime has taken place or is occurring or about to occur." Mere presence in a high-crime area cannot supply the necessary reasonable suspicion. ( In re Tony C. , supra , 21 Cal.3d at p. 893, 148 Cal.Rptr. 366, 582 P.2d 957.) Here, the complaint was of otherwise undescribed "harassing" conduct. There was no information indicting threats, trespassing, battery, physical assault, or weapons. There was no information the person had been asked and refused to leave the business. This was not a description of *1117criminal conduct, and at the hearing, the People made no assertion that this "harassment" was criminal, nor did they suggest what criminal offense this conduct might have constituted.6 Nothing about defendant's conduct, sitting on the sidewalk, wearing a jacket, sweatshirt, and pants suggested he was engaged in or about to engage in criminal activity.
A person approached by police for questioning "need not answer any question put to him; indeed, he may decline to listen to the questions at all and may go on his way. [Citations.] He may not be detained even momentarily without reasonable, objective grounds for doing so; and his refusal to listen or answer does not, without more, furnish those grounds." ( Florida v. Royer (1983) 460 U.S. 491, 498, 103 S.Ct. 1319, 1324, 75 L.Ed.2d 229, 236 ; see also Illinois v. Wardlow (2000) 528 U.S. 119, 125, 120 S.Ct. 673, 676-677, 145 L.Ed.2d 570, 577.) Thus, the fact that defendant refused to provide his identification and tried to walk away from the officers did not provide them with reasonable suspicion sufficient to justify his detention.
"[A] frisk for weapons is not justified unless the officer can point to specific and articulable facts which, considered in conjunction with rational inferences to be drawn therefrom, give rise to a reasonable suspicion that the suspect is armed and dangerous." ( People v. Medina (2003) 110 Cal.App.4th 171, 176-177, 1 Cal.Rptr.3d 546.) A claim of "harassing" customers of a business, with no reports of violence, battery, assault, threats or weapons does not reasonably suggest the presence of weapons. Nor did defendant's conduct, or wearing a jacket and sweatshirt on a "pretty warm" day provide reasonable grounds to believe he was armed and/or dangerous and might gain immediate control of a weapon. ( People v. Miranda (1993) 17 Cal.App.4th 917, 927, 21 Cal.Rptr.2d 785.) Thus, there was not reasonable *97suspicion to patsearch defendant once he was detained.
In this case the officers did not have sufficient information that a crime had been committed or was about to be committed and defendant was the person who had committed that crime. There was no reasonable suspicion for them to detain defendant or patsearch him. The motion to suppress should have been granted. Because the motion to suppress was erroneously denied, the judgment must be reversed.
*1118DISPOSITION
The judgment is reversed and the case remanded to the trial court with instructions to vacate its order denying the motion to suppress, enter a new order granting the motion to suppress and conduct further proceedings in accordance with the law.
