Police in Chicago have made public photographs of a man they allege assaulted a woman on a CTA Blue Line train in the Old Irving Park neighborhood. The release follows an incident earlier this month in which a woman reported being touched while seated behind her on the train.

The Chicago Police Department says the suspect was identified through surveillance footage and other investigative methods. The images show the individual from multiple angles and are being distributed to the public in hopes of confirming his identity.

The alleged assault occurred on a Blue Line train traveling through Old Irving Park in September 2026. The victim reported that the man placed his hand on her without consent while the train was in motion. No further details about the victim or suspect have been released.

Police have asked anyone who may have seen the suspect on the train or who can provide additional information to contact authorities. The department emphasized that the release of the photographs is part of an ongoing investigation and does not constitute an arrest.

The CTA has reiterated its policy of zero tolerance for harassment and assault on its vehicles. It encourages riders to report any suspicious behavior to train operators or law enforcement.

The investigation remains active, and police have not disclosed a timeline for potential charges. The public release of the suspect’s photo marks a continued effort by the department to solve the case and ensure safety on public transit.
