Video shows police beating a Maryland student after Duke game

When boozed-up Maryland fans ripped down street signs, shouted obscenities and attempted to tip over a city bus after last month's victory over rival Duke, police made 28 arrests and quickly subdued the riot.

Based on this video of Maryland student John McKenna getting brutally beaten, however, questions are now being raised over whether the officers used excessive force.

The newly released video shows McKenna skipping down the street when he encounters two police officers on horseback and backs away from them. Seconds later, three officers in riot gear check the student into a wall and beat him with batons, leaving him unconscious, bruised and bleeding in the street with a gash in his skull large enough to require multiple stitches.

The officers gave a sworn statement at the time alleging that McKenna "struck those officers and their horses, causing minor injuries." The statement also claims McKenna was inciting the crowd and describes his injuries as being caused when he was "kicked by the horses."

Charges against McKenna have since been dropped.

"This is police brutality, pure and simple," Chris Griffiths, McKenna's lawyer, told ABC News. "Clearly, the charging document is a lie. As you can see from the tape, there is not a single fact in that document which is true."

An investigation of the incident by Prince George's County Police Chief Roberto Hylton has so far resulted in the suspension of one of the officers identified by the tape. Hylton said that other officers involved in the beating will likely be fired.

"I was outraged," said Hylton. "I was very disappointed at the conduct that I saw on the part of my officers on the video tape."
