Roseville, CA- Five men and a Rocklin teenager were arrested in connection to a $1.5 million jewelry smash-and-grab robbery that took place last year at the Westfield Galleria mall in Roseville, police said Thursday. Three masked robbers smashed glass display cases Nov. 21 at S&L Gem Co. Jewelry using hammers and sledgehammers, said Lt. Chris Ciampa, a spokesman for the Roseville Police Department. The suspects face charges of robbery, conspiracy, vehicle theft and evading police, police said. Anuanu Tuiono, 20; Siafa Fifita, 23; Dahnavan Tuipulotu, 20 and Sione Halaapiapi, 18, all pleaded not guilty at their respective arraignments, according to Placer Superior Court records. It is unclear if a 15-year-old boy will face charges. He was not identified by police because he is a minor.
