UPDATE: Training Grenade Causes Bomb Scare in Calabasas Gated Community

Residents of a gated community in Calabasas were evacuated from their homes Monday after a gardener reported finding a grenade in a backyard, but bomb squad investigators later found the device to be a dud, police said.

The grenade was reported at 4:21 p.m. in the 24700 block of Calle Largo, said Lt. Robert Wiard of the Los Angeles County Sheriff's Department.

Nearby homes were evacuated as a bomb squad was called to the scene, he said.

Investigators examined the device and determined that it was a training grenade because it had been hollowed out, authorities said.

Residents were allowed back into their homes around 7:50 p.m.
