FBI special agents and Fairfax County police are looking for a man who robbed an Alexandria bank, and they are asking the public for information that can help identify the perpetrator.

It's the second time in less than six months that authorities have sought information about a robbery at the TD Bank at 6615 Richmond Highway in the Beacon Hill area.

About 2:30 p.m. March 23, a man walked into the TD Bank, demanded money from the teller and implied that he had a weapon.

The teller handed over cash to the man, who then fled on foot across the bank parking lot in the direction of the Chili's restaurant.

The money given to the robber contained a dye pack, which exploded with red ink, police said.

Surveillance video captured grainy images of the robber, and authorities are hoping that someone will recognize a still shot photo of the man and call in with a tip.

The robber is described as a light-skinned black male with a round face, wearing square glasses, a black hat, gray raincoat and light blue jeans. He was about 5-foot-10 and 170 pounds with a medium build.

Anyone with information about the culprit can call the FBI at 202-278-2000 or visit tips.fbi.gov. They can also call Fairfax County police at 703-691-2131 or by texting "TIP187" plus the message to 274637.

It's not the first time the Alexandria bank has been highlighted in The Washington Examiner's weekly "Bank Heist" feature. In October, a man dressed in construction hard hat and yellow reflective construction vest with orange stripes robbed the TD Bank, and hopped into a white Dodge Grand Caravan that had a sticker on the driver's side door that may have read "Metro" and had a yellow light on top.

Authorities are still looking for information in that case, too.
