Chicago Police issued a South Side community alert after the second attack on a teenage girl in two weeks.
Police said a 15-year-old girl was walking near 95th and Prairie Wednesday morning when a man walked up behind her. He started talking to the girl, police said, then pulled out a gun. He forced her into a nearby yard and sexually assaulted her.
A stranger in the area assisted the girl after the suspect ran away, police said.
The man was described as a teen about 17 years old wearing a black skull cap, black hoodie, jeans and tan Timberland boots. He's black with a light complexion, standing about 5-foot-7 and weighing about 120 pounds, police said.
Last week a 13-year-old girl was sexually assaulted as she walked to school in the Englewood neighborhood.
Police said the man approached her, started talking to her, then pulled out a blue steel handgun. He forced the girl in a nearby alley where he sexually assaulted her before running off.
Police are urging parents not to let their children walk alone, and the Guardian Angels plan to escort students to school Friday morning at 95th and Michigan. The Angels also will hold a rape awareness seminar at Harper High School at noon Saturday.
