ORLANDO, Fla. (AP) -- Hundreds of students have been evacuated from a dorm on the University of Central Florida campus in Orlando after explosives devices were found while authorities were investigating a death.

Police were called to Tower 1 early Monday after a fire alarm went off. Arriving officers found a man dead from what appeared to be a self-inflicted gunshot wound. Police told local TV stations they found an assault weapon and improvised explosive devices on the scene.

About 500 students were evacuated from the dorm and a parking garage was closed.

The university has cancelled classes through noon Monday as a precaution.

A statement on the university's website said the UCF Arena will open Monday morning to accommodate displaced students.

It was not immediately known whether the dead man is a student.
