A Connecticut man has pleaded guilty to bank robbery.  56-year old Alvin Robertson of Bridgeport also admitted to committing three bank robberies and robbing two subway stores last year. 

Last May, Robertson robbed a sandwich shop on Ethan Allen Highway in Ridgefield.  He brandished a knife, pointed it at the store clerk and demanded money with a threat to kill the clerk.  Last July he indicated he had a gun while robbing a Subway in Monroe. 

Robertson also robbed a People’s Bank branch in Monroe last August, one in Watertown in September, and one in Berlin. 

He faces up to 20 years in prison when he is sentenced at a later date.  Robertson has prior federal and state bank robbery convictions.
