A convicted felon was arrested on suspicion of cultivating marijuana and possessing stolen property, an ammunition cache and cocaine after a LoJack device led authorities to a commercial building in Rancho Cucamonga, officials said Thursday.

Omar Medina, 33, of Los Angeles, was booked into the West Valley Detention Center and was being held on $100,00 bail, according to the San Bernardino County Sheriff’s Department.

The Ontario Police Department’s aviation unit requested assistance on Sept. 8 when a LoJack indicated that a stolen portable welder, housed on a trailer, was in the area of 6th Street and Archibald Avenue in Rancho Cucamonga, the Sheriff’s Department said in a news release.

Rancho Cucamonga police officers responded to the area and determined that the LoJack signal was emanating from a business in the 10000 block of 6th Street (map), the release said.

Medina opened a rolled-up door to the building after being contacted by the officers, who then saw the welder “in plain sight” with the identifiable markings the owner had described, authorities said.

When police entered the business, they noticed a large pallet of more than 40,000 rounds of rifle ammunition, a trailer containing motor vehicles, and a “strong odor of marijuana” near the rear of the building, according to the Sheriff’s Department.

A search warrant was later executed at the location and 141 marijuana plants where discovered. Six stolen vehicles were also found at the site, including sand rail all-terrain vehicles, trailers and motorcycles.

Medina was arrested for possession of stolen property, felon in possession of ammunition, cultivation of marijuana, and possession of cocaine.

An investigation is ongoing. Anyone with information is asked to call the Rancho Cucamonga Police Department at 909-477-2800.
