Man charged with assaulting former employee outside Nashville courthouse — Robert Joiner arrested

57-year-old Robert Keith Joiner was booked into the Metro Nashville Jail Tuesday on an outstanding warrant alleging he grabbed a former employee by the neck as he was exiting the courthouse and pushed him into a wall where he continued to assault the victim and take his cell phone, which he was using to record. The victim was treated for a hip and head contusion at a local hospital. A commissioner released Joiner, who is from Colorado, on his own recognizance without posting a bond.
