Victoria’s anti-corruption agency, IBAC, is investigating a video of a policeman caught kicking a driver in the head while arresting him following a pursuit in Melbourne’s south-east at the weekend.

Latham Murphy had allegedly driven on the wrong side of the road and sped at almost 130km/h an hour before officers swooped on him on Taldra Crescent, Seaford, on Saturday afternoon.

Video filmed by a witness, known only as ‘Greg’, shows Mr Murphy being pushed to the ground, as another male officer approaches and kicks him in the chest.

“Hey! What the f—k was that you dog,” Greg yells, while the accused’s sister, Emma Murphy, screams at police.

The officer then appears to take out a can of OC spray and tells people at the scene to “get away”.

Ms Murphy described the officer’s conduct as “disgusting”.

The accused's sister spoke to 9NEWS about the incident. (9NEWS) (9news)

“They jumped on him and started hitting him. I (think) it was uncalled for,” she said.

“No sister should ever have to see that. I’m only young, I didn’t want to see my brother get hurt.”

9NEWS understands the Professional Standards Command has viewed the footage and is investigating. It has referred the matter to IBAC, who will conduct a separate probe.

Police allege Mr Murphy had been driving erratically on Frankston-Dandenong Road with no number plates and at 128km/h in an 80km/h zone.

He has been charged with a number of offences, including failing to stop when signalled by a police officer, driving dangerously, driving while disqualified, driving an unregistered car, failing to drive to the left of a median strip and possession of the drug ‘ice’.

He has also been charged with reckless conduct, with police alleging he tried to escape the grasp of an officer by steering the wheel of the car.

The 22-year-old faced the Frankston Magistrates Court this afternoon and has been remanded in custody.

He is expected to return to court on May 23.
