By the time medics loaded Boyd into the back of an ambulance, he reportedly had physical injuries imposed by officers....

The report does not describe Boyd as violent or threatening, saying Boyd seemed to scratch the author’s neck and accidentally kick another officer, named Garland, “while trying to stand”. Boyd grabbed a third officer’s face, the report said, describing his hand slipping down to the officer’s badge and microphone. That officer, Bowman, “delivered two closed fist strikes to the suspect’s face with his right fist”.

Francis-Williams said: “He is literally attacked. And by attacked, I mean the witness (Styron) is describing that he (was) struck many times and struck to the ground.

“Officer Bowman is the one that when he arrived, really started wailing on Mr Boyd, meaning Mr Boyd was on the ground in a prone position and Bowman sat on him, almost straddled his back, and put his left arm under Boyd’s neck and pulled his head up in a choking fashion.”A 21-year-old man died in a hospital near Baltimore on Wednesday, after an altercation with county police officers who repeatedly punched him as they responded to a call for an ambulance.
