MEMORANDUM OPINION AND ORDER
JAMES B. ZAGEL, District Judge.
Plaintiff Alberto Hinojosa has brought this action against the City of Chicago, Sergeant Richard Maher, Officers Nicolas Garcia, Ruben Martinez, Jr., and Sergio Escobedo, and Jose Marquez for various civil rights violations under 42 U.S.C. § 1983 including false arrest, failure to intervene and civil conspiracy, as well as related state law claims. Craig Lawrence, initially an additional plaintiff in this action, has since voluntarily dismissed his claims, which were Counts I, II, VI and VII of the First Amended Complaint. Defendants now move for summary judgment as to Sergeant Maher on Counts III, IV, V, VII, IX, and X. In a separate motion, defendant Jose Marquez moves for summary judgment as to Count V. For the following reasons, summary judgment as to Sergeant Maher is granted, and summary judgment as to Jose Marquez is denied.
Mssrs. Hinojosa and Lawrence were both arrested on May 13, 2010 for impersonating a police officer. That day, Mr. Hinojosa had hired Mr. Lawrence, a private investigator, to help him find his vehicle, which Mr. Hinojosa believed had been stolen. The two men soon found what they believed to be Mr. Hinojosa's vehicle sitting on a driveway at 2337 South Millard Avenue in Chicago. They determined that the driveway was being rented by Mr. Marquez, obtained his phone number, and called him. What was said on the phone is in dispute, but Mr. Marquez soon arrived at the driveway and, upon being asked to produce proof of ownership of the vehicle, then agreed to drive home to get the vehicle's title papers.
While driving home, Mr. Marquez called his friend, Officer Escobedo, for advice and assistance. What was said between the two men is also in dispute, but Mr. Marquez then drove to pick up Officer Escobedo, and they both returned to 2337 S. Millard Avenue.
About the time that Mr. Marquez and Officer Escobedo returned to the driveway, Officers Maher, Garcia and Martinez also arrived on the scene. Exactly what prompted the presence of these officers is in dispute. Plaintiff contends that Officer Maher, and through him Officers Garcia and Martinez, arrived on the scene in response to a 911 call from Mr. Lawrence asking for police assistance with a stolen vehicle investigation. Defendants contend that the three officers arrived on the scene in response to an anonymous "hand-waver's" report that a man was impersonating a police officer at that address.
The remainder of the narrative is largely in dispute as well. Citing, inter alia, the hand-waver's report and Plaintiffs' attire,  Defendants claim to have had probable cause to arrest both Plaintiff and Mr. Lawrence for impersonating a police officer. Plaintiff, on the other hand, contends that he overheard Officers Escobedo, Garcia and Martinez converse with Mr. Marquez in Spanish and devise a plan wherein Mr. Marquez would accuse Plaintiff and Mr. Lawrence of impersonating police officers. In so doing, Mr. Marquez would create a pretext for the officers to take Plaintiff and Mr. Lawrence into custody, thereby diverting attention away from Mr. Marquez and the purportedly stolen vehicle. Plaintiff contends that Officer Maher, who does not speak Spanish, did not participate in the conversation, but, as the supervising officer on the scene, approved the arrest either knowing or recklessly disregarding that it was a sham.
In any event, Plaintiff and Mr. Lawrence were indeed arrested and transported to the 10th District police station. They were released approximately four and a half hours later after questioning. In the end, neither individual was charged with impersonating a police officer.
Summary judgment should be granted when "the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law." Fed.R.Civ.P. 56(c). A genuine issue of triable fact exists only if "the evidence is such that a reasonable jury could return a verdict for the nonmoving party." Pugh v. City of Attica, Ind., 259 F.3d 619, 625 (7th Cir. 2001).
Once the moving party has set forth the basis for summary judgment, the burden then shifts to the nonmoving party who must go beyond mere allegations and offer specific facts showing that there is a genuine issue for trial. Fed.R.Civ.P. 56(e); see Celotex Corp. v. Catrett, 477 U.S. 317, 323-24 (1986). The nonmoving party must offer more than "[c]onclusory allegations, unsupported by specific facts" in order to establish a genuine issue of material fact. Payne v. Pauley, 337 F.3d 767, 773 (7th Cir. 2003) (citing Lujan v. Nat'l Wildlife Fed'n, 497 U.S. 871, 888 (1990)). A party will be successful in opposing summary judgment only if it presents "definite, competent evidence to rebut the motion." EEOC v. Sears, Roebuck & Co., 233 F.3d 432, 437 (7th Cir. 2000). I consider the record in the light most favorable to the non-moving party, and draw all reasonable inferences in the non-movant's favor. Lesch v. Crown Cork & Seal Co., 282 F.3d 467, 471 (7th Cir. 2002). I will accept the non-moving party's version of any disputed fact, however, only if it is supported by relevant, admissible evidence. Bombard v. Fort Wayne Newspapers, Inc., 92 F.3d 560, 562 (7th Cir. 1996).
During the course of briefing, Defendants withdrew their summary judgment motion as to Officers Escobedo, Martinez and Garcia. This was a sensible decision, as there remain in this case clear questions of material fact with respect to the alleged liability of these individuals. Defendants did not, however, withdraw their motion as to Officer Maher. This, too, was a sensible decision.
[T]o be liable [under § 1983] for the conduct of subordinates, a supervisor must be personally involved in that conduct. Supervisors who are merely negligent in failing to detect and prevent subordinates' misconduct are not liable. The supervisors must know about the conduct and facilitate it, approve it, condone it, or turn a blind eye for fear of what he might ...
