LEWISTON — Two men charged with robbing a local TD Bank on Saturday had already served sentences in connection with separate earlier bank robberies.

Joseph Richards, 46, of New Hampshire robbed the Lisbon Street bank of about $8,690 shortly before 9 a.m., wearing a yellow hooded sweatshirt and blue mask and showing a black handgun, according to police and court documents. He vaulted a teller counter, removed the cash from the tellers’ drawers and stashed it in a black trash bag, according to the documents.

Police said Neil West Sr., 64, of Portland drove the getaway dark blue Chrysler Town and Country minivan that was parked across the street at a Sullivan Tire store.

A high-speed police chase on the Maine Turnpike followed, ending when a Maine State Police cruiser rammed the minivan in Saco. West was arrested after a short foot chase. Richards fled the scene, but was arrested shortly after 11 a.m. roughly a mile away.

A backpack he was carrying contained nearly $10,000, according to court records. Police also recovered a black handgun that appeared to be a real firearm, but was likely a BB or pellet gun, according to the documents.

West was convicted in 2012 in U.S. District Court in Portland for being an accessory after the fact to bank robbery. A year later, he was sentenced to 41 months in prison plus three years of supervised release.

Richards, who also was on supervised federal release at the time of his Saturday arrest, had been sentenced in New Hampshire federal court in 2003 to 151 months in prison for robbing a Citizens Bank, according to court papers. He was ordered to pay $1,475 in restitution. He also was sentenced to three years of supervised release. He was also serving a state court sentence at that time.

Richards was charged on Saturday with one count of bank robbery, punishable by up to 20 years in prison and a fine of up to $250,000; West was charged with accessory after the fact, a charge punishable by up to 10 years in prison and a fine of up to $125,000.
