Police responded to reports of an explosive device at a movie theater in Howell Friday night.

Officials say they arrested 24-year-old Jacob Cavanaugh of Manchester. Cavanaugh is an employee at Xscape Theatres on Route 9.

Another employees apparently pointed Cavanaugh out to security, which then prompted a search of his car.

Two handguns were said to be inside the car, one of them reportedly was loaded. A hand grenade was also found, but it was not active.

Police do not believe Cavanaugh intended to do harm.

About 500 people had to be evacuated Friday night.
