The San Diego Police Bomb Squad and a HAZMAT crew were called to Barrio Logan Monday to investigate a possible grenade.
Plumbers doing work on a home in the 3100 block of Boston Avenue discovered what they thought was a grenade underneath the house, according to police.
The discovery was made around 4:15 p.m. By 6 p.m., crews determined that the object was safe and started clearing the scene. Officers took the grenade to dispose of it properly.
