BALTIMORE — Police have arrested a man suspected of assaulting an on-duty Maryland Transit Administration police officer, leaving the officer unconscious near a subway station in Baltimore.

The Baltimore Sun reports that the officer was taken to a hospital after Friday’s attack to be treated for injuries that weren’t considered life-threatening.
