Three men were recently arrested for various offenses including possessing heroin and methamphetamine after authorities said they monitored white supremacist gang members in Costa Mesa.

One of two traffic stops on Friday resulted in the seizure of $12,000, heroin, a quarter pound of methamphetamine, a taser, two batons and a digital money counter, the Costa Mesa Police Department said in a statement.

Earlier in the day, authorities seized meth, a loaded semi-automatic handgun, ammunition and drug paraphernalia after a 1:30 p.m. stop in the 2400 block of Newport Boulevard.

Brian Jay Bishop, 35, of Trinidad, Texas was arrested on suspicion of meth for sale, possession of a concealed and loaded firearm while possessing drugs and possessing a firearm but not being the registered owner, authorities said.

Since the arrest, Bishop posted bail and was released.
