A 19-year-old Riverside man was arrested near UC Riverside after officers making a traffic stop found a loaded revolver, 26 pounds of marijuana, and a quantity of butane honey oil during a search of the vehicle, police said Tuesday.

The officer who made the stop at Iowa Avenue and Blaine Street found “evidence indicating the driver was selling various types of marijuana, including the concentrated ‘butane honey oil’ cannabis,” a news release said.

The car was originally pulled over at 11:18 a.m. Monday for a traffic violation, but a records check showed the driver, John Jacobsen, had a felony warrant for his arrest, leading to a search of his car.

The loaded gun was found under the front passenger seat of the car. It was not registered to Jacobsen, but he claimed to own it, the release said.

Jacobsen was arrested on suspicion of possession of a loaded and concealed firearm inside a vehicle and possession of marijuana for sale, as well as the outstanding warrant. The cannabis and the gun were confiscated as evidence. He remained in custody Tuesday at the Robert Presley Detention Center in Riverside.

The traffic stop was made by an officer assigned to the University Neighborhood Enhancement Team, a cooperative alignment between the Riverside Police Department and the UC Riverside Police Department.
