The footage shows Demitre Clarke-Oliver approach PC Tse from behind and grab him by the shoulder before punching him in the face and bolting away.
Another police officer followed him and was finally able to catch him. He tried to fight that officer as well but fell to the floor and was cuffed.
Tse had to get an operation to insert two plates and eight pins to reconstruct his jaw.
Clarke-Oliver pled guilty and was sentenced to two years in prison.
“To attack a police officer is a cowardly and despicable act. PC Tse was responding to a call from the public at the time, and despite the calm and professional conduct from the officers, Clarke-Oliver attacked PC Tse from behind without provocation or warning and then ran away, said superintendent Joe Kidman, LPA Commander for Oxford.
“He then threatened another officer before being subdued and arrested. It is to PC Tse's great credit that despite the serious injury to his jaw he assisted in this arrest.”
“This incident is a sobering reminder of the risks that our officers willingly take every day and night to keep our city safe.”
“We are also reminded of the impact this has on our officer's families and loved ones who provide such valuable support despite knowing the risks they face.”
