Chicago’s Civilian Office of Police Accountability has opened an investigation into allegations that Chicago police officers engaged in sexual misconduct with migrants, including at least one who was under 18 years old.

Andrea Kersten, COPA’s chief administrator, said her office has not identified any migrants claiming to be victims of sexual assault or any form of sexual misconduct by police officers. But she said the update was necessary given the “unprecedented amount of media attention and public scrutiny” the allegations had received thus far. COPA is an independent, civilian agency that conducts administrative investigations into certain allegations of police misconduct.

The investigation was sparked on July 6, she said, when her office received information from city employees alleging sexual misconduct involving an officer assigned to the Chicago Police Department’s 10th District.

“The allegation identified a specific officer, accused him of sexual contact with an unidentified, underage, female migrant, and indicated that several other unidentified officers from the 10th District may have also been engaged in similar misconduct,” Kersten said at a Tuesday news conference.

Chicago facing an influx of immigrants

Chicago is among multiple U.S. metro areas challenged by an influx of hundreds of immigrants from the southern border, including many bused to those cities from Texas beginning in the spring. About 11,000 have arrived in Chicago since August 2022, according to Cristina Pacione-Zayas, Mayor Brandon Johnson’s deputy chief of staff, and some families have found shelter in the lobbies of police stations.

COPA’s special victims unit, she said, contacted the Chicago Police Department’s bureau of internal affairs to see whether they were investigating or aware of the allegations. While the source of the initial allegation remains unknown, “the information appeared to be circulating” among department employees as well as among staff of the city’s office of emergency management and communication.

Given the severity of the allegations, Kersten said her office is allocating “significant resources” to the investigation, including a dozen investigators, many with expertise in sexual misconduct investigations and/or who are fluent in Spanish.
