A woman was sexually assaulted on a Chicago Transit Authority Blue Line train bound for the Loop Monday afternoon, according to an alert Tuesday by Chicago police.
The 41-year-old woman got on an eastbound train at the Oak Park Avenue station a little after 3 p.m., police said. Soon after, a male who got on the train at the Forest Park station attacked her from behind.
He knocked her to the ground, sexually assaulted her, and then robbed her of her iPhone and cash, police said.
After the attack, he got off the train at Cicero. He then rode a westbound train to the Austin station, police said.
The suspect was described as a black male wearing a gray and blue Columbia jacket. He wore blue jeans and gym shoes with green laces, police said.
Anyone with information on the assault is asked to call Area North detectives at (312) 744-8261.
