Law enforcement agencies are asking the public to help identify the man responsible for an armed robbery at a Taunton bank on Christmas Eve. 

The Federal Bureau of Investigation, the Massachusetts State Police and the Taunton Police Department are looking for a bank robber they’re calling the "Christmas Eve Bandit." The bandit  allegedly robbed the First Citizens Federal Credit Union branch at 280 Winthrop St. in Taunton on Dec. 24, 2014. Officials are offering up to $10,000 for information leading to the arrest of the robber. He is considered armed and dangerous.

The male suspect allegedly entered the bank, said, "Merry Christmas," followed by an obscenity and ordered the tellers to empty their cash drawers and fill a black duffle bag with money, according to authorities. He allegedly had an assault rifle with a banana clip capable of shooting a 7.62 millimeter round, possibly an AK-47, authorities said. He then fled on foot, wearing a black mask, blue jeans, black jacket, gray sweatshirt, black boots and black gloves. His age and race are not known.

The public can view photos and surveillance video of the robber here.
