Long Beach police arrested three men on suspicion of felony firearm possession Friday evening after initially pulling them over for a license plate violation, authorities said.

Officers were conducting “proactive enforcement” near 28th Street and Pine Avenue shortly before 6 p.m., spokeswoman Shaunna Dandoy said.

The officers found two handguns and ammunition and discovered the three men in the car were legally prohibited from possessing firearms. Someone can be barred from having firearms in California for a number of reasons including outstanding warrants, previous felony convictions or temporary restraining orders.
