Administrators at Brook Park School in LaGrange Park placed the school on soft lockdown for about 55 minutes on Tuesday morning after a student reported a potentially dangerous situation during an outdoor physical education class.

According to LaGrange Park police, at about 10:50 a.m., a second-grade student reported that a vehicle drove by the school and an occupant in that vehicle possessed “an object that may have resembled a weapon.”

The vehicle made no attempt to stop as it drove by, no one in the vehicle attempted to communicate with students or faculty and there were no verbal threats or gestures, police said.

District 95 Superintendent Mark Kuzniewski told the Landmark that about 130 children were on the playground when the vehicle drove past the school northbound on Harrison Avenue and that just one student reported seeing something out of the ordinary.

Security cameras at the school caught the vehicle as it drove past, said Kuzniewski, and there was nothing in the video to suggest any danger. The passenger side window of the vehicle was open about halfway, Kuzniewski said. The vehicle turned right and headed east toward Maple Avenue on 29th Street.

“It was probably a very low-danger incident,” Kuzniewski said.

Despite that, Kuzniewski said the school was placed on immediate lockdown and police responded to the school, which is located at 30th Street and Raymond Avenue.

The school serves students from the Proviso Township portions of Brookfield and LaGrange Park in kindergarten through fifth grade. Police searched the area and determined the area safe.

“You want to investigate if there’s a concern,” said Kuzniewski. “Police were incredibly responsive.”

The lockdown was lifted at 11:45 a.m. Police reported that officers will continue to be present during drop-off and pick-up times and will increase patrols in the area.
