Kentwood High School was in an emergency lockdown this morning because a handcuffed man escaped police custody and went onto campus after a traffic stop.

Police pulled the man over near the traffic circle just north of the campus for a traffic violation at 8:20 a.m., according to authorities. The suspect was handcuffed when the officer discovered the man had some outstanding warrants for his arrest.

At 8:26 a.m., the suspect fled police custody and ran onto Kentwood’s campus. The school went into emergency lockdown, but the suspect had already gained access to one of the buildings.

Chris Loftis, public information officer for Kent School District, said the man tried to elude police by hiding in an office. He said the school’s security used surveillance cameras to locate and apprehend the still-handcuffed suspect and returned him to police custody.

There was no threat to students and there were no weapons involved, Loftis said.

The school was in lockdown for about an hour to ensure things were all clear. Loftis attributed the speedy recovery of the suspect to the school’s security and surveillance system.

“[The surveillance system] worked perfectly,” he said. “We had a very quick and positive resolution.”
