A psychiatric patient at E.C.M.C. went on a rampage nearly two years ago, and the video is just surfacing now.

The video from June 15, 2014, was obtained by WIVB-TV through a freedom of information request, and shows patient Sidoles Lubin, Jr. grabbing a mental health aide by the neck and throwing her. Moments later Lubin punched another nurse in the head, and then bit another employee in the stomach.

Sidoles Lubin, Jr. was sentenced to assault and was sentenced to two years in state prison.

Since the incident, officials at E.C.M.C. say that the staff training has increased significantly.
