Maryland, Calvert County and federal authorities are investigating whether a Halloween mask-wearing robber who held up a Dunkirk bank Friday has also hit other banks throughout the Washington area.

A man walked into Prince George's Federal Savings Bank on Route 260 about 9 a.m. Friday and pointed a gun at employees, said Detective Sgt. Greg Cameron of the Maryland State Police. The masked robber demanded to speak with the bank manager, who took him to the bank's vault, Cameron said. The robber also demanded money from tellers in $50 and $100 bills, Cameron said.

Police described the mask as a "celebrity mask" that covered the entire head and face. No one in the bank fully recognized the character depicted by the mask, police said

Less than a mile away in Anne Arundel County, police later found the robber's getaway car -- a black Chrysler sedan that had been reported stolen in Prince George's County.

The robbery bore similarities to one at the Dunkirk SunTrust Bank three months ago, state police and Calvert County detectives said. On Dec. 18, three men wearing similar Halloween masks and armed with guns robbed the SunTrust and fled in a stolen car they later discarded in Anne Arundel, said Calvert sheriff's office detective Michael Moore.

A direct link between the robberies has not been established. Anyone with information about either robbery can call the Maryland State Police at 410-535-1400 or the sheriff's office at 410-535-2800.
