A Santa Barbara man suspected to be the "red Sharpie bandit" was arrested last week.
Investigators believe Anthony William Frisco, 44, is responsible for 15 bank robberies in Southern California, four of them in San Luis Obispo County.
Santa Barbara police arrested Frisco on Dec. 17.
Frisco is suspected of robbing two Wells Fargo branches on Dec. 14, one inside the Vons store in the Marigold Center off Broad Street in San Luis Obispo and one on West Tefft Street in Nipomo.
He is also suspected of robbing a Rabobank in Pismo Beach on Aug. 1 and a Chase branch on Oct. 27 in San Luis Obispo.
The nine other bank robberies Frisco is suspected of happened in Orange County, according to authorities.
Frisco is being held in the San Luis Obispo County Jail on $500,000 bail. Local authorities had the most evidence to charge him with the crimes. The Orange County robberies are still under investigation.
His notes in the past have been written with something resembling a red Sharpie, law enforcement officials said.
