(Updated at 3:45 p.m.) Police responded to Pentagon City mall this afternoon after a fight broke out between two groups of people.

The call originally came in as a report of a man spotted with a gun near the Capital One Bank, on the food court level. Police took five people into custody near the Pentagon City Metro station, and soon determined that the initial report of a gun was erroneous.

The five people initially taken into custody were all banned from the mall, according to Arlington County Police spokeswoman Det. Crystal Nosal. One of the men was arrested for assaulting another man, she said, and the other four were released from custody.
