The Oro Valley municipal complex, 11000 N. La Cañada Drive, was evacuated and the campus locked down Thursday afternoon after a man came into the police station seeking to dispose of a grenade that turned out to be live.
The man, who resides in California, brought the grenade in at 2:36 p.m. for disposal. The grenade was a World War II souvenir that belonged to his father, who was moving into a retirement home. The man and his father believed the grenade was inert.
Following explosive ordinance protocol, a police sergeant placed the grenade in a small desert area west of the police building. Oro Valley police officers then began an immediate evacuation of the police building and surounding town complex, said Oro Valley police Lt. Chris Olson
Members of the Pima County Regional Bomb Squad inspected the grenade and determined it was live. It was placed in a detonation container and transported to the Naranja town site for counter-detonation.
La Cañada Drive was closed in both directions between the south entrance to the town hall and north to Naranja for two hours.
People can drop off weapons and ammunition to the police department; however, the Pima County Regional Bomb Squad advises all Pima County citizens to dial 9-1-1 if they need ordinance or other explosive material removed from their home or business. Bomb technicians will respond and remove the ordinance or material. Citizens are advised to not transport ordinance or explosive material under any circumstance, said Lt. Olson.
