A former Brent police officer who violently attacked an abusive drunk while on duty has been jailed for three months.
Shamed Andrew Graham, repeatedly kicked the 'obnoxious' man in the back and left him lying limp on the floor after the shocking assault, on January 31 this year.
The officer was on patrol with a colleague, when they came across Mahdi Jamal sleeping on a bench in Barham Park, Wembley.
Jamal began swearing at the uniformed cops and told them to leave, prompting Graham to arrest him for drunk and disorderly behaviour.
However, before he was handcuffed, the burly PC lead the rough sleeper to a secluded part of the park and sweep his legs away, before battering him on the floor.
Graham was reported by two shocked colleagues who were called to the incident for backup and convicted after an investigation by the Met's Directorate of Professional Standards.
JPs at the City of Westminster Magistrates Court told the shamed officer he had abused his position of power, before sentencing him to 12 weeks in prison on .
Detective Inspector Helen O'Sullivan, from the Directorate of Professional Standards, said: "This behaviour fell far below the high standards the Metropolitan Police expects from its officers.
"The vast majority of officers are professional and honest and it is their responsibility to ensure the minority who act inappropriately are brought to account.
"I would like to praise the officers who did the right thing and came forward in this case."
The former prison warden, who joined Brent Police in 2002, quit his post shortly after the incident.
He received a police commendation for bravery in 2004 for helping save the life of a man who had been stabbed in Harlesden.
