PORTERVILLE, Calif. (KSEE/KGPE) - Three people were arrested after being found with concealed and unregistered firearms during a traffic stop, the Porterville Police Department said. Officers say they conducted a traffic enforcement stop on a vehicle at the 1500 block of West Olive Avenue on Saturday around 9 p.m. The reason for the stop was due to equipment violations.
