SEATAC, Wash. (AP) — A King County sheriff's spokesperson said the bomb squad detonated a grenade that was found near an elementary school in the city of SeaTac.
Sgt. Cindi West says a construction worker found the grenade in a box on a street corner Monday morning.
West says bomb technicians determined the grenade was real, but an X-ray analysis showed it did not contain any explosives. They took the grenade to a remote location where it could be safely detonated.
"The grenade appeared to be an old cast iron grenade and may have been a training device," she said.
School was not in session because of the winter break.
