A 31-year-old woman was raped at knifepoint early Sunday morning in the West Side Humboldt Park neighborhood, police said, adding that it wasn't the first such attack by the suspect -- a Hispanic man with a Mohawk haircut.
About 1 a.m. Sunday, the victim was walking on North Avenue between Homan and Pulaski when a man driving a small blue 4-door vehicle approached, accoring to an alert from Grand Central Area detectives.
The man forced the victim into an alley in the 1400 block of Monticello, where he held a large knife to the victim and sexually assaulted her.
The attacker is known to have sexually assaulted prior victims, all of whom who have "high-risk" lifestyles, while displaying a knife.
Police said the attacks occurred in the 14th and 25th police districts, which inlcudes the Humboldt Park and Logan Square neighborhoods, but would not provide further information about previous attacks.
He is described as a 35-year-old Hispanic man with a medium complexion who stands between 5 feet, 7 inches and 5 feet, 8 inches tall with a stocky build. He wears his hair in a long Mohawk pulled to a pony tail in the back, and the sides of his hairline are shaved. He also has a tattoo of a cross on his right shoulder.
