PROVIDENCE — A Pawtucket man was sentenced yesterday to more than three years in prison for robbing Pawtucket Credit Union in March 2007.

William Harper, 41, received the 37-month sentence for taking about $3,600 from Pawtucket Credit Union on Broadway, according to a news release from U.S. Attorney Robert Clark Corrente’s office.

Harper pleaded guilty in October to bank robbery.

Prosecutor Zechariah Chafee said at the plea hearing that the government could show that on March 14, 2007, Harper, wearing a ski mask, went into the credit union at 540 Broadway. According to the news release, when Harper did not get attention at a teller window, he went to another teller, pushed in front of a customer, and thrust a plastic bag toward the teller, saying, “Fill this bag. Hurry up.”

The teller put about $3,600 in the bag and Harper fled.

He was arrested at his Woodlawn Avenue apartment about a month later. Prosecutors said that after detectives confronted him with bank surveillance photos, he admitted to the robbery.

The Pawtucket police and the FBI investigated.
