A Maryland man has been arrested for allegedly attacking and robbing an 87- year-old Arlington resident.

The incident took place around 4:50 p.m. Saturday afternoon on the 3800 block of 9th Street N., in the Virginia Square area. Police say Melvin Baxter, 57, grabbed the 87-year-old man by the neck and threw him to the ground before robbing him of the cash in his wallet and fleeing on foot.

“A witness immediately came to the assistance of the victim and contacted police, providing a detailed description of the assailant,” according to an Arlington County Police Department press release. “The victim sustained minor injuries and was treated by medics on scene. At approximately 5:00 p.m., an officer located and detained the suspect on the platform of the Ballston Metro Station.”

Baxter, a Capitol Heights, Md. resident, was charged with robbery and held without bond at the Arlington County Detention Facility.
