CNN) -- Authorities found a body and a bag of improvised explosive devices in a dormitory tower at the University of Central Florida early Monday, prompting officials to cancel classes at the Orlando school until at least noon, a school spokesman said.
Police went to the dorm after getting a call about a person with a gun sometime after midnight. Hundreds of students were evacuated from the tower, and police found a male dead of a self-inflicted gunshot wound in a bedroom, school spokesman Grant Heston said.
Police also found an assault weapon and a bag of improvised explosive devices there, Heston said. The FBI has been contacted, he said.
Heston didn't say whether the dead person was a student, or release a name.
