VISTA, Calif. -- The leader of a group dubbed the "Fat Boy Bandit" responsible for robbing seven North County Banks and a video store was sentenced today in Vista to 12 years in prison.

Arturo Ulloa, 28, pleaded guilty in an earlier hearing to 11 counts of robbery.

He was sentenced by Superior Court Judge Daniel Goldstein.

Two other defendants, Fredy Carrillo and Dwayne Scott Depenning, pleaded guilty earlier.

The robberies, which occurred between August 2006 and December 2007, were initially reported to be the act of a lone "husky" man weighing almost 300 pounds -- later identified as Ulloa.
