A police sergeant has been found guilty of two counts of common assault.
The sergeant aged 30 who is attached to Hackney Borough was found guilty on July 25th.
He had pleaded not guilty throughout the trail.
The court heard that PS Pilbeam, who is currently suspended, assaulted a 27-year-old man who refused to pick up some paper he had discarded on the floor, twisting his ear and standing on his foot.
The incident which happened on 2 March 2013 occurred after the man had been searched under the Misuse of Drugs Act by other officers.
One of the officers on duty at the time reported the assault to the MPS Directorate of Professional Standards (DPS) which investigated the incident and, following CPS advice summonsed the officer for the offence in November 2013.
Deputy Assistant Commissioner Fiona Taylor, DPS, said: “Sergeant Pilbeam’s actions towards a vulnerable man are inexcusable and have no place in the Met.
“I commend the actions of the officer who had the strength of character and belief that if he reported this wrongdoing it would be dealt with appropriately.
“We must remember that MPS officers and staff engage with the public millions of times each year and the vast majority of those contacts are carried out with professionalism and courtesy.”
PS Charles Pilbeam will be sentenced on Thursday, 7 August at St Albans Crown Court.
