A drunk driver who bit and kicked a police officer who pulled him over has been jailed for three years and eight months.
James Forrester, 33, of no fixed address, admitted assault, drink driving and violently escaping lawful custody at Manchester Crown Court.
The court heard that on 8 November 2010, he bit through the officer's cheek as they sat in his patrol car.
Forrester then followed him out of the car and kicked him to the ground.
The judge also disqualified Forrester from driving for five years and told him he would have to take an extended driving test.
The court heard that at about midnight, the traffic officer was on Stockport Road in Levenshulme, when he pulled over Forrester's blue Ford Focus that had no lights on, a deflated tyre and smashed side mirror.
Forrester got into the back of the police car but failed to provide a breath sample and then punched and bit the officer as he tried to handcuff him.
After chasing the officer out of the car he kicked him in the head and body, the court was told, and only stopped when four passers-by came to help the victim.
Forrester was arrested nearby and found to be two-and-a-half times over the drink drive limit.
'Violent and sustained'
The officer required stitches to his cheek and suffered a severe fractured cheekbone and severe bruising.
Det Con Andy Middleton, said: "Forrester was putting members of the public at risk by drink driving and when stopped by the officer launched an unprovoked, violent and sustained attack.
"The only reason he stopped the attack was thanks to the intervention of the four men who saw what happened and chased him off before helping with the officer's injuries until an ambulance arrived.
"There is only one place for someone who has such a blatant disregard for the law and those employed to uphold it and I am pleased he has today been jailed."
