Fayette County Public Schools canceled all student activities at Lafayette High School after the detonation Wednesday. District spokeswoman Lisa Deffendall told the Lexington Herald-Leader two other bombs were also found on campus and deactivated.
Deffendall says a search turned up no bombs at other schools and no one was injured by the explosion.
The bombs were made out of soda bottles and the explosion happened at about 8:30 a.m. as the school's marching band color guard practiced on a parking lot behind the school.
Superintendent Tom Shelton says there was no warning phone call or social media message received by the school.
