COLUMBUS, Ohio, Sept. 25 (UPI) -- An explosion at the police headquarters in downtown Columbus, Ohio, was caused by a battery in construction equipment, police said.
Police evacuated the building at 7:25 p.m. EDT Tuesday after someone inside reported a loud noise that sounded like an explosion.
FBI and anti-terrorism investigators searched all eight floors of the building, along with the basement, and found no sign of an attack, said Sgt. Rich Weiner, spokesman for the Police Division.
Police Chief Kimberely Jacobs said police discovered the noise was caused by an exploding battery in a hydraulic ladder that was being used to add insulation inside the building. The ladder was inside the lobby of the building, The Columbus Dispatch reported Wednesday.
