Authorities believe the man who looted a PNC bank in Alexandria Monday is the same person who robbed the Bank of America on Washington Street the week before, and an Arlington Bank December 14. The FBI is now involved.

The suspect should be considered dangerous, according to a flyer released by the FBI’s Washington Field Office.

At about 2:10 p.m. Monday a man entered the PNC Bank on Diagonal Road in Alexandria, implied he had a weapon and demanded money, Alexandria police said. The teller relinquished an undisclosed amount of cash and the suspect fled the area. No one was injured.

Federal and local agents want the suspect for a December 20 bank robbery at the Bank of America on Washington Street in Alexandria and for a December 14 bank heist in Arlington.

Authorities will not release the amount of money taken because it could complicate the investigation, Alexandria police spokesman Jody Donaldson said.

Police describe the suspect, who’s image has been caught on surveillance cameras, as a black male, six feet to 6-foot-6.

Monday’s bank robbery was Old Town’s second in a week and Alexandria’s fifth this year.

Witnesses can choose to remain anonymous. Informants can call the FBI’s Washington Field Office at 202-278-2000 as well.
