Authorities say they destroyed a pair of Civil War-era cannon balls on display at a Georgia college after officials realized they were live.
Kennesaw State University spokeswoman Tammy DeMel says a bomb squad removed the relics Monday from the third floor of the social sciences building after authorities became concerned they posed a danger. The building was evacuated as a precaution and students were let back in later.
Cobb County Sgt. Dana Pierce says the bombs had been detonated and that it would be hard to know if they could have gone off on their own.
According to a school press release, the cannon balls have been in a display case in a room of the social sciences building for three years at the college just north of Atlanta.
