INGLEWOOD, Calif. — A Lawndale man was facing possible felony charges today after deputies found a grenade and other military items in his vehicle during a traffic stop in Inglewood, authorities said.

Oscar Briseño, 27, was arrested after deputies stopped his 2007 Acura for an expired registration about 8:40 p.m. Monday in the 300 block of Manchester Boulevard, the sheriff’s department reported.

“During their investigation, deputies could smell the odor of burnt marijuana coming from the vehicle,” a sheriff’s department statement said.

“During a search of the vehicle for the source of the marijuana, deputies found a marijuana smoking pipe that smelled like burnt marijuana,” the statement said. “Deputies also found an AR-15 magazine loaded with ammunition, two .50-caliber armor-piercing rounds, a U.S. military ballistic vest, and a 40mm grenade.”

Explosives experts were sent to the scene to remove the items.

Briseño allegedly obtained the military items from the U.S. Marine Corps, from which he reportedly had been discharged, according to the sheriff’s department.

“Due to Briseño’s arrest taking place near Claude Hudnall Elementary School, he was arrested for possession of an explosive device near a school,” the sheriff’s department reported. He was also booked on suspicion of theft of a military destructive device.

Briseno was held on $500,000 bail, and was scheduled to appear today in court in Inglewood.
