A girl on Wednesday said she was walking to Oak Terrace Elementary School when a woman in a white minivan approached her and asked her to get into the car for a ride, police said.
A day earlier, another girl said she was approached by a man in a newer model, dark-green SUV with a lift kit and large tires near Highwood Ball Park around 3:30 p.m. She told police the man asked her if she wanted a ride and drove away when she refused.
The man was described as a white male with fair skin in his late 40s with gray hair. He was wearing sunglasses, police said.
North Shore School District 112 alerted parents, students and faculty to remain on high alert.
"Our schools and our police departments work closely together to help ensure student safety," a statement sent to parents this week read. "The police departments take all reports seriously, and investigate them to the fullest extent possible."
Three other luring attempts were reported in recent weeks. In one report, an 8-year-old boy on his way home from Oak Terrace School said he ran from a man who offered him a ride home.
Another incident involved a 7-year-old girl approached last month near the same school. She said the man told her he knew her dad and wanted to give her a ride. The girl ran back into the school
Police released a sketch after last month's reports but said that besides the first two instances, there are no common descriptions of the suspects or vehicles involved.
Police on May 9 released this sketch of a woman who approached a girl outside Oak Terrace Elementary School in Highwood a day earlier and offered her a ride.
A man matching this likeness approached a girl near Highwood Ball Park on Wednesday afternoon, police said.
Police say two men matching these sketches approached kids outside Oak Terrace Elementary last week.
