In this latest case, police said a 13-year-old girl was walking through an alleyway on the 10000 block of Bronx Avenue between 7 a.m. and 7:39 a.m. when she was approached by a man inside a vehicle.
The man waved to the girl and tried to get her to go with him, police said. The teenager refused and ran to the bus stop at Lavergne Avenue and Old Orchard Road as the suspect drove away, police said.
The man was described as being between 60 and 70 years old, with gray hair and heavy face wrinkles. He was wearing round-shaped glasses and a blue shirt with red suspenders, police said.
Police said the suspect was reportedly driving an older model light blue four-door vehicle. The make and model are unknown at this time, police said.
Since the first full week of September, police have reported a child abduction attempt case every week. But police say they have no reason to believe the four cases are related since descriptions of the suspects and their vehicles have been different every time.
"We're taking all of these incidents very seriously and following up with serious investigations," Deputy Chief Tony Scarpelli said. "It's important (for the community) to know safety rules and follow precautions."
Anyone with information on the attempted child abductions should call the Skokie Police Department's Investigation Division at 847-982-5900. If suspicious activity is occurring, witnesses should call 911 immediately.
