PRESQUE ISLE, Maine — Police fatally shot a man who was shooting a handgun behind a business at 174 Main St. across from the University of Maine at Presque Isle.

The man, whose name has not been released, was firing the gun into the air and the ground, refusing to drop the weapon or speak with law enforcement, Presque Isle Police said.

After trying to negotiate with him for about 50 minutes, the man allegedly threatened officers with the gun and an Aroostook County Sheriff’s deputy fatally shot him, police said.

The case has been turned over to the Maine Attorney General’s office.

UMPI Safety Officer Fred Thomas said police told him there was an armed man behind Cook Florist across from the university at noon.

“We did put the campus on lockdown and had everyone shelter in place,” Thomas said. The campus has reopened.

Police were still there after 2 p.m. and had blocked the portion of Main Street between the UMPI entrances, diverting both northbound and southbound Route 1 traffic through the campus.
