PHOTO: Pima Regional Bomb Squad responded to reports of a grenade in Green Valley Thursday morning. According to a release from Green Valley Fire, a Sonoita resident brought what he believed to be a live grenade to Station 153. The man told firefighters that he found the grenade on his son's property, and he didn't know what to do with he so it brought it to the fire station. The station and crews were evacuated and taken out of service until it could be determined if the grenade was live or inert. The Pima County Sheriff's Office was notified, and the Pima Regional Bomb Squad was mobilized and responded. Bomb technicians X-rayed the grenade and determined it was inert and did not pose a threat. Traffic on north Abrego at the intersection of Continental was closed during the incident.
