The Arlington County Police Department has charged Antwan Raynor, 26, of Capitol Heights, Md., with one count of armed robbery.
Raynor is accused of robbing the City Market & Deli, 2250 Clarendon Blvd., at knifepoint shortly after 9 p.m. Friday, according to information police released this week.
Raynor allegedly entered the convenience store wearing a grey ski mask, pulled a knife on the clerk and demanded cash from the register, according to police. He then grabbed $222 and ran from the scene.
Officers say they caught the man shortly afterward at the nearby Metro stop. He is being held without bail.
