Investigators say they found a body, and then turned up a bag of explosive devices in a dorm at the University of Central Florida early Monday.
The school canceled classes until at least noon and several hundred students were evacuated from the area, KRMG has confirmed.
The call came in to 911 shortly after midnight as a man with a gun, police say.
Neither the school nor police have released any information about the dead man, so it remains unclear if he was a student.
They found a male dead in a dorm room, apparently the result of a self-inflicete gunshot, according to a school spokesman.
The FBI has reportedly joined the investigation.
