Several Placentia businesses were evacuated Wednesday, Nov. 29, after a hand grenade was found in a box of donations at a Goodwill thrift store and donation center.

Around 2:15 p.m. employees at store, located at 1101 E. Imperial Highway, told officers an elderly woman dropped off a box of donations and then left, Placentia police Sgt. Adam Gloe said in a statement.

When the employees began going through the box a short time later, they discovered the grenade, he added.

Several businesses in the shopping center where the Goodwill store is located were evacuated. The Orange County Sheriff’s Department Bomb Squad safely removed the grenade and rendered the store safe, Gloe said. No one was injured.

The hand grenade was found to be inert, said Sheriff’s Department Lt. Wayne Rehnelt.

It is unknown if there was any criminal intent associated with the grenade, said Gloe.
