According to police, the below video was shot moments after the suspect, 20-year-old Donovan Lawson, attempted to fare-beat at the Myrtle Avenue-Broadway JMZ station yesterday just before 8 p.m.

The nightstick-wielding officer apparently approached Lawson and asked to see his ID, a request that Lawson denied. The officer responded by attempting to cuff Lawson, which he resisted. Be warned that the action of this video is all contained within the first few seconds, and it's not pleasant.

Lawson was taken to Woodhull Hospital and treated for cuts to his head. He has been charged with fare beating, resisting arrest, disorderly conduct and obstructing government administration.

The officer was taken to Wyckoff Heights Medical Center and treated for injuries to his hand and arm. The incident is being investigated by the department's Internal Affairs bureau.
