Michael Accianto, 39, was arrested at the Nassau County Probation Office, located in Mineola, on Friday after he reported for a scheduled visit.
Investigators claim Accianto's robbery spree began on May 27 when he allegedly robbed a Bank of America, located at 5310 Sunrise Highway, in Massapequa. He is then accused of striking a Wachovia Bank, located at 3584 Long Beach Road in Oceanside on June 9.
In July, police say Accianto robbed two banks: a Chase Bank, located at 4210 Sunrise Highway in Massapequa and a Bank of America, located at 2443 Hempstead Turnpike, in East Meadow.
In August, Accianto again struck in Massapequa, this time robbing a Roslyn Savings bank, located at 6199 Sunrise Highway, police said.
Accianto was charged with five counts of robbery in the third-degree and one count of attempted robbery.
He is slated to be arraigned Saturday in First District Court in Hempstead.
