Damning CCTV footage released by a court shows a police officer shoving a train commuter into the wall of a cell and then throwing him to the floor after the man failed to show identification.

Dean Bradley Anderson, 40, a senior constable once commended for bravery, is likely to lose his job of 13 years after he was found guilty of four counts of assault in Melbourne Magistrates Court on Thursday.



Anderson was found by magistrate Elizabeth Lambden to have assaulted commuter Anton Perry on December 13, 2012 in a police cell at Flinders Street station.



CCTV footage of the assault was released by the court late on Thursday and obtained by Fairfax Media on Friday.
