CEDAR FALLS (AP) — Police say a Halloween getup apparently caused a scare that led to a search at the University of Northern Iowa in Cedar Falls.

Police searched the campus Wednesday night after receiving a report of a man with a gun.

Authorities concluded the man, who was dressed in military fatigues and had his face painted, was likely toting a plastic pistol as part of a costume.

Campus police spokeswoman Milissa Wright says authorities were called about 8:30 p.m. after a report of a suspicious man at Maucker Union, where a costume party was being held.

Wright says police didn’t find the man. But after interviewing witnesses, they believe he was carrying a fake gun.
