The FBI and D.C. police are looking for a man who robbed a Northwest D.C. bank and made a getaway in a taxi -- all while showing support for the District's baseball team.

The man walked into the TD Bank branch at 1753 Connecticut Ave. NW shortly before noon on Oct. 5, wearing a dark suit, black sunglasses and a Washington Nationals baseball hat. He also was carrying a grocery bag and was seen wearing a latex glove on at least one hand.

The man placed the grocery bag on a counter and handed a note to the teller, which stated that there was a bomb inside the bag and demanded money, according to Andrew Ames, spokesman for the FBI's Washington field office.

The teller gave the man an undisclosed amount of money before he left the bank, leaving the grocery bag behind. Witnesses saw the man walk a few blocks on Connecticut Avenue NW before hailing a taxi to make his escape, Ames said.

Authorities inspected the package and found its contents were not dangerous.

Ames said investigators think a taxi driver might recognize the man and hope someone saw where he got out of the vehicle.

Authorities described the suspect as a white male in his late 20s to early 30s, about 5 feet 8 inches tall and weighing between 150 pounds to 190 pounds.

Anyone with information about the robbery is asked to call the FBI at 202-278-2000 or D.C. police at 202-727-9099. Those wishing to remain anonymous can text the police at 50411.
