A man from Washington state was arrested in Ukiah on Saturday on suspicion of possessing a gun, drugs and large mortar-style fireworks, according to police.

While on patrol, two police officers saw a GMC Yukon SUV fail to stop at a stop sign in the 100 block of South Main Street in central Ukiah shortly after 1:20 a.m.

Officers pulled the vehicle over for a traffic enforcement stop during which they found a black handgun behind the center console. The driver, 51-year-old Grady Gavin Hollenbeck, was asked to exit the vehicle. As he exited the vehicle, officers saw a glass methamphetamine pipe in the drivers side door pocket.

According to Ukiah police, Hollenbeck was detained in a patrol vehicle as officers searched the SUV using probable cause.

During the search, officers found a plastic pencil box in the passenger seat containing cocaine, methamphetamine and oxycodone tablets. Additional drug paraphilia was also found in the vehicle, according to police.

The gun, which officers saw upon pulling over the vehicle, was identified as a Glock model 20. A loaded magazine was found next to the gun.

Officers also found a backpack containing large consumer-grade mortar-style explosive fireworks, which are illegal in California. The Sonoma County Sheriffs Office bomb squad later collected the fireworks for safe destruction.

Hollenbeck was booked into Mendocino County Jail on five counts, including two felonies, specifically possession of a loaded firearm with controlled substances and possession of a destructive device.
