(Chicago Tribune) — Two Chicago police officers are under criminal investigation amid explosive allegations they played strip poker with a young woman and sexually assaulted her in her Far North Side apartment while on duty early Wednesday. At a news conference, an outraged Terry Hillard, the interim police superintendent, noted he is a father before calling the officers’ conduct “inappropriate. You just can’t justify it.” He referred to the allegations as “heinous criminal activity.” Hillard said at least one of the officers allegedly sexually assaulted the woman. The officers were arrested later Wednesday and questioned at Belmont Area headquarters with legal counsel present before being released without charges. The criminal inquiry continues as investigators collect “evidence and forensics,” Hillard said. Cook County prosecutors have been notified about the allegations. In the meantime, the 10-year veterans were relieved of police powers and put on administrative duty, he said.
