ORDER GRANTING MOTION TO DISMISS IN PART AND DISMISSING ACTION WITH PREJUDICE

Plaintiff Aaron Singer sued the Indianapolis Metropolitan Police Department ("IMPD") and four of its officers in their official capacities, alleging violations of his constitutional rights during several interactions he had with law enforcement in 2025. Dkt. 21. As relief he seeks only damages. Defendants moved to dismiss the amended complaint. Dkt. [22]. For the reasons below, that motion is GRANTED in part because IMPD is not a proper party and because the City of Indianapolis—the real entity sued in a claim against IMPD officers in their official capacities—is not subject to federal RICO liability. This Order also addresses Defendants' motion to show cause, dkt. 47, and Singer's cross-motion for sanctions, dkt. 51. While discovery was pending, Singer sent hundreds of threatening and harassing emails to Defendants' counsel, some of which threatened sexual violence against counsel. At a telephonic status conference on February 26, 2026, the Magistrate Judge assigned to this case admonished the parties and directed them to "limit all communications with each other to matters that are solely within the scope of

the claims currently before the Court." Dkt. 45 at 2. In her post-conference minute order, the Magistrate Judge warned, "If a party to a claim engages in unprofessional, disrespectful conduct towards others involved in the litigation, the Court may dismiss the claim with prejudice." Id. Singer did not heed this warning. Defendants' motion demonstrates that Singer continued to send inappropriate, threatening, and harassing emails to counsel despite the February 26 order to refrain from this conduct. Accordingly, the Court finds that

Singer abused the judicial process in bad faith and willfully violated the Magistrate Judge's February 26 order by continuing to send inappropriate, threatening, and harassing communications to opposing counsel. The Court GRANTS Defendants' motion for cause, dkt. [47], DENIES Singer's cross-motion for sanctions, dkt. [51], and as a sanction against Singer DISMISSES what remains of his claims with prejudice. The remainder of the motion to dismiss, dkt. [22], is DENIED AS MOOT. I. BACKGROUND

In evaluating motions to dismiss under Rules 12(b)(1) and 12(b)(6), the Court accepts all well-pleaded factual allegations in the complaint as true and draws all reasonable inferences in the plaintiff's favor. Franzoni v. Hartmarx Corp., 300 F.3d 767, 771 (7th Cir. 2002); Thompson v. Ill. Dep't of Prof'l Reg., 300 F.3d 750, 753 (7th Cir. 2002). The Court does not, however, credit legal conclusions. Thompson, 300 F.3d at 754. A. Singer's Claims

Singer alleges that IMPD and its officers violated his First, Fourth, and Fourteenth Amendment rights during several interactions in early 2025. The first interaction took place on January 22, 2025. Singer was homeless at the time. Before getting off an IndyGo bus at the Carson Transit Center in downtown Indianapolis, Singer asked the driver to radio ahead to inform IndyGo personnel that he wanted to speak with a manager. Upon arrival, he encountered uniformed IndyGo security personnel who he claims unlawfully detained him and searched his pockets without his consent. IndyGo security

was later joined by IMPD officers, who searched his backpack without his consent. No one informed him of the grounds for his arrest. When an IndyGo manager arrived, she spoke only to the officers and not to Singer. IMPD officers then transported Singer to the Marion County Jail, "subjected [him] to a warrantless and nonconsensual blood draw and fingerprinting," strip-searched him, placed him on suicide watch, denied him a phone call, and "held [him] in a brightly lit room overnight alongside other fully naked detainees." Dkt. 21 at 8. Singer was released the next day without charges.

The second incident took place on February 25, 2025. After speaking with a woman who identified herself as having recently experienced police misconduct, Singer approached three IMPD officers standing on the street corner nearby and "asked whether they upheld the Constitution in their interactions with the public." Dkt. 21 at 10. He described his own experiences on January 22. "The officers then appeared uneasy, and shortly thereafter dispersed from the area without further discussion." Id. Later that afternoon, Singer visited the

College Avenue Branch of the Indianapolis Public Library. After he departed, his former roommate was "confronted in the library restroom area by IMPD officers" who questioned her. Id. IMPD officers then followed her to her residence, where they encountered Singer. The officers claimed they had received a report from the roommate that she felt unsafe around him. The roommate later told Singer she had not made any such report. Singer and his roommate both reported being disturbed by the encounter with police. Id. at 12. When Singer visited IMPD headquarters on March 8 to lodge a complaint about the February 25

incident, officers refused to clarify the justification for their behavior and spoke to Singer "in a demeaning manner." Id. at 13. Singer understands these interactions to "reflect[] a deliberate and coordinated pattern of harassment and intimidation directed at [him] in retaliation for his protected speech and his efforts to seek redress for prior constitutional violations" and "an institutional policy, custom, or tolerance of retaliatory behavior toward complainants of police abuse." Id. The third incident took place on March 9, 2025. Singer visited the Irsay

Family YMCA at CityWay in downtown Indianapolis, where he was a member, and requested access to the chapel. The YMCA staff "responded in an erratic and illogical manner, ultimately threatening to ban [Singer] from the premises." Dkt. 21 at 14. The staff then contacted IMPD officers, who "declined to hear [Singer's] side of the story," "spoke exclusively with YMCA personnel," and "summarily escorted [Singer] out of the building under threat of force." Id. The fourth incident took place on June 22, 2025. Singer was physically

assaulted while riding an IndyGo bus in Indianapolis. He got off the bus at 42nd Street and College Avenue and walked to a nearby Indianapolis Fire Department station to seek medical assistance. The firefighters "failed to provide medical aid," "refused to summon an ambulance," and "did not contact law enforcement for assistance," mocking and dismissing Singer instead. Dkt. 21 at 16. When Singer was walking near the same fire station later that day on the way to a convenience store, an IMPD patrol vehicle forced him into the station's parking lot. When he "informed the officers that he was currently pursuing federal civil

lawsuits against IndyGo, IMPD, and the Marion County Sheriff's Office," the officers brought him to the ground, handcuffed him, and transported him to the Marion County Jail. Singer remained incarcerated for four days. He later left the state on court permission "for his safety," and charges were eventually dismissed. Dkt. 21 at 18. Singer alleges that he is "a law-abiding adult" with "no criminal record" and "has had no substantive interactions with the Indianapolis Metropolitan Police Department prior to the incidents described herein." Dkt. 21 at 19. He
