CORCORAN — A probation compliance check at a home in Corcoran led to the discovery of a “chop shop” operation, California Highway Patrol officials said.

During the probation check, CHP investigators said they found an engine from a stolen 2005 Chevrolet Silverado pickup truck inside the garage of 32-year-old Francisco Javier Montes.

In addition to the stolen engine, investigators said they found several rounds of high-powered rifle ammunition and narcotics at the premises.

CHP officials said the check happened Friday with help from the Kings County Gang and Narcotic Task Force and detectives from the Kings County Sheriff’s Office Agricultural Crimes Unit.

After finding the stolen engine, investigators said they determined Montes was operating a chop shop at his residence, and he was subsequently arrested and booked into the Kings County Jail.
