Police on Tuesday released surveillance images of a man suspected of sexually assaulting and robbing a woman at knife-point while riding a Chicago Transit Authority Red Line train last week.
A 26-year-old woman told police last Friday that she was attacked shortly before 5 a.m. on a southbound train between Roosevelt Road and 79th Street. The attacker got off the train at the 87th Street station, police said.
The attacker was described as a black man between the ages of 20 and 25. He had a slim build, dark complexion and no facial hair. He was wearing a black hooded jacket and all black clothing, and was armed with a black-handled knife with a long blade, police said.
Police said the woman was alone in the car when she was attacked. It’s unclear how far the car was from the first car, in which the conductor might have heard or seen something.
The woman refused medical treatment, police said.
CTA spokeswoman Catherine Hosinski said police notified the agency after the alleged assault. The CTA provided surveillance footage to detectives.
