Police investigating reports of a man with a gun at a University of Central Florida dorm found a student dead from an apparently self-inflicted gunshot wound—and explosives and firearms in his room. All morning classes have been cancelled, and the dorm has been evacuated.

Police were called to Tower 1, a 500-student dorm, just after midnight on Monday morning, apparently on a report of a person with a gun.

Police found the man dead from what appears to be a self-inflicted gunshot wound. Authorities have since interviewed several witnesses and they have confirmed the man was a student. It's not clear where his body was found.

Heston said they have not found any type of a written plan or manifesto in the man's room. He said the man's body, the weapons and the explosive devices were all found in one of the rooms in the man's dorm apartment.

Law-enforcement officers investigating the incident found a handgun, an assault weapon and and improvised explosive devices, a campus spokeswoman said.

Counseling is being made available to dorm residents. All non-essential UCF employees have been told to stay home.
