FOX LAKE, Ill. (AP) — Police in northern Illinois say a manhunt is underway after an officer was shot and killed while pursuing a group of suspicioustimthumb.php men.

Lake County Sheriff’s Office spokesman Sgt. Christopher Covelli says the officer radioed in Tuesday morning to tell dispatchers he was chasing three men on foot, but communication with him was lost shortly after.

Covelli says the officer’s backup arrived to found him injured with a gunshot wound and that the officer died at the scene.

He was killed in Fox Lake, 55 miles north of Chicago. Undersheriff Raymond Rose tells the Chicago Tribune that the officer was stripped of his gun and other equipment.

Law enforcement officers are conducting a massive manhunt with helicopters, dogs and officers on foot. Nearby Grant Community High School has been locked down.
