• Bolingbrook Student Nearly Abducted Tuesday: Police

On Tuesday, police reported a man tried to pull a Bolingbrook student into his car. Then on Thursday, a second teenage girl reported fighting off a man who followed her home and grabbed her from behind, according to police. 

Bolingbrook police have said Thursday's incident may be related to the attempted abduction on Tuesday. Both incidents remain under investigation, police said.

Valley View posted this alert to parents on its website: 

“Please remind your children to not talk to strangers when they are walking to and from school. If a stranger does approach your children, they should not talk to him or go with him. Tell your children to report any suspicious adults to you, their teacher, or the office.”

Thursday's attempted abduction

A 16-year-old girl said she was followed home from Bolingbrook High School into her apartment building in the 300 block of Woodcreek Drive. A man then grabbed her from behind as she entered the second floor of the building. The victim fought off her attacker and he fled west on foot toward neighboring Plimmer Park. 

The offender was described as a stocky, black man about 5'5" tall, wearing a red jacket. The incident was reported at 2:11 p.m.
