A man suffered a large cut during an attempted robbery outside the Crystal City Metro station early Sunday morning.

Police say the man was outside the Metro station around 4:00 a.m. when a male suspect approached him from behind and asked for a cigarette. The suspect then demanded money and when the victim refused to hand over any cash, the suspect took out a knife and slashed him across the right forearm, police said.

“The victim sustained a large laceration and was transported to Virginia Hospital Center,” said police. “The suspect is described as a black male, approximately 5’7” tall and 180 lbs. He was wearing a black t-shirt, blue jeans and black sneakers at the time of the incident.”

The suspect is wanted by police on expected charges of malicious wounding and attempted robbery.
