Prince William County police are asking for the public's help identifying the man who robbed a Woodbridge bank on Tuesday.

Investigators released a surveillance image of the man they say held up the Bank of America branch in the 2600 block of Prince William Parkway.

The man walked into the bank about 5 p.m., claimed to have a weapon and demanded money. He fled on foot after taking an undisclosed sum.

No one was hurt.

The robber was described as a black male, 23 to 28 years old, five feet ten inches tall, with a heavy build.

Anyone with information is urged to call Crime Solvers at 703-670-3700 or 1-866-411-TIPS. There's cash reward up to $1,000.
