A Chicago police oversight agency charged with investigating sexual misconduct allegations between police officers and migrants housed at the station, has been unable to substantiate the claims made by an unknown source.

On Tuesday, the Civilian Office of Police Accountability (COPA) provided an update to reporters on its investigation into claims that a police officer assigned to the 10th District of Chicago participated in sexual misconduct with a migrant.

The chief administrator of COPA, Andrea Kersten, said the agency received information on July 6 about an allegation of sexual misconduct involving at least one police officer within the district.

The allegation identified a specific officer and accused that officer of having sexual conduct with an underaged female migrant. The tipster also indicated several other officers in the 10th District may have engaged in similar misconduct, Kersten added.

COPA staff assigned to the special victims unit reached out to the Chicago Police Department’s bureau of internal affairs to see if it had an investigation open on the matter or were aware of the allegations.

The agency learned that although the source of the initial allegation was unknown, information was circulating among various police department and Office of Emergency Management Communication employees. Later that evening, two tracking numbers were assigned to the investigations into Chicago Police Department misconduct — one for COPA’s investigation and the other for the Bureau of Internal Affairs’ potential investigation.

Kersten said the agency allocated significant resources into determining whether any wrongdoing took place and to identify who reported the allegations.

"This investigation remains open and ongoing, but I can confirm that to date, we have not identified any migrants claiming to be the victim of sexual assault or any form of sexual misconduct by CPD members," Kersten said.

She also said the investigation led to additional complaints involving migrants, including an allegation of unidentified officers in the 19th District engaging in sexual misconduct with an unknown migrant.

As a result of the investigations from both COPA and the Bureau of Internal Affairs, the city began moving migrants out of the station.
