Law enforcement officers are investigating a bank robbery in Alexandria and asking the public for information that could help them in the case.

Police said the suspect wore a scary Halloween mask when he walked into the Capital One Bank at 500 S. Washington Street around 9:45 a.m. on Oct. 20. The man implied he had a weapon and demanded money. The teller gave the suspect an undisclosed amount of cash, and the man fled the area. No one was injured.
