(AP) â€" Police officers in a Central California town took part in a scheme in which cars belonging to poor Hispanic people were impounded, towed and later sold or given away for free to some officers when the car owners couldn't pay the fees, authorities said Tuesday. Four King City officers â€" including the recently retired police chief and the acting chief â€" have been arrested in the scheme, and two others were also arrested Tuesday on unrelated charges, Monterey County District Attorney Dean Flippo said. Early Tuesday morning, teams from the Monterey County sheriff's office, the FBI, the Salinas Police Department and the district attorney's bureau of investigation arrested the officers after a months-long investigation. The four officers tied to the alleged car theft scheme have each been charged with bribery, accepting a bribe or embezzlement. Officer Jaime Andrade was accused of possession of an assault weapon and illegal storage of a firearm, and Officer Mark Allen Baker was arrested on suspicion of criminal threats. Owner Greg Bailey, who also works as a correctional officer at a nearby prison, said he has known Miller for a long time and is skeptical about the charges. Husband Hector Vasquez said there's frequent talk in the U.S. of how corrupt Mexican law enforcement agents are. King City Manager Michael Powers told The Associated Press that Monterey County sheriff's deputies and officers from the nearby cities of Gonzales and Soledad have volunteered to help police the city now that so many of its officers have been taken off duty.
