A 15-year-old girl was approached by a man in a black, four-door Mercedes Benz after leaving Richards High School in Oak Lawn around 4:55 p.m. Tuesday, Oak Lawn police said.
The girl was walking south on Central Avenue when the driver pulled up to her and asked her to get in the vehicle. He opened the passenger side door of the vehicle, police said.
The girl said "no," and he left the scene. Her mother called police when she got home. She was not injured.
The offender is described as a Hispanic, 25 to 35 years old with medium length hair. He was wearing a black T-shirt and jeans, officials said.
The black Mercedes has silver handles and a silver pinstripe across its doors, according to the girl.
No other incidents have been reported in the area, but schools have been notified of the situation.
