Tape shows US police beating student
A newly-surfaced video showing US police officers brutally beating up an unarmed university student has provoked outrage across the US. John McKenna, 21, the University of Maryland student is still recovering from the physical injuries he suffered last month when he got caught up in a celebration of his school basketball team's win over Duke. The newly-released video, which has been aired extensively on US TV, shows three police officers in riot gear ramming the student and then beating him with batons. Left unconscious in the street, McKenna suffered a concussion and bruises on his arms.
