A man posing as a Walmart employee took over a cash register at a Fairfax County store and stole money after checking out a customer, police say.

The man, who was wearing a Walmart employee vest, entered the store in the 13000 block of Fair Lakes Shopping Center in Fairfax, Virginia, at around 4 p.m. on Dec. 15 and told a cashier that he was needed in the office.

Fairfax County Police say the man then took over the register and even checked out a customer before stealing an undisclosed amount of cash.

He then left the store and drove away in a silver Honda.

Officials released details of the incident Wednesday, including surveillance images of the suspect. Police say the suspect may have also stolen from Walmart stores in Farmville, Virginia, and in Maryland.

The suspect is described as a black male between 5 feet 9 inches and 6 feet 1 inch tall, and weighing 170 to 180 pounds. He was wearing a white T-shirt and a Walmart employee vest.
