Bomb Squad Investigates Hand Grenade in Unincorporated Monrovia

The Sheriff's bomb squad investigated a hand grenade left behind by a man following an altercation between neighbors in an unincorporated Monrovia neighborhood Monday, according to authorities.

Sheriff's deputies responded to a domestic disturbance call in the 2400 block of Lincoln Avenue at about 6:04 p.m. on Monday and saw a grenade left behind by a man involved in the altercation, according to Operations Sgt. Gary Morgan of the Sheriff's Arson/Explosives Detail.

Deputies called in the bomb squad. A diagnostic test was later performed on the grenade and it was determined to be harmless, Morgan said.

"It was inert, meaning there was no explosive ordinance inside," Morgan said.

The incident sprang out of a dispute between neighbors, according to Terrence Williams, a member of the Monrovia-Arcadia-Duarte Town Council. The man who left the grenade lived in a back unit on Lincoln Ave. and he was upset that the people living in the front unit refused to pay for his broken car window, according to Williams.

Sheriff's deputies blocked off Lincoln Avenue from Schrode Avenue to Camino Real while bomb squad detectives investigated the grenade, Williams wrote in an email. No suspect has been taken into custody, Morgan said.
