ORLANDO, Fla. — Authorities investigating an apparent suicide discovered weapons and explosive devices in a dorm on the University of Central Florida campus in Orlando early Monday, and hundreds of students were evacuated, though the school said there was no immediate threat.

University police were called to the dorm around 12:20 a.m. after a fire alarm went off, UCF spokesman Grant Heston said. While they were on their way to the scene, a 911 call came in about a man with a gun.

Arriving officers found a man dead from what appeared to be a self-inflicted gunshot wound inside a residence at the Tower 1 dorm.
