The parents of a man who was arrested on Friday in Sydney's south-west claim police officers should be charged, after dramatic footage capturing the arrest was shared online.
Police had spotted Jacob Wiles while patrolling Riverside Drive in Airds and believed he was wanted on an outstanding warrant.
Police allege he "took off" in a car, which stopped on Riverside Drive after a short time.
They asked the 21-year-old to exit the car, in which it is understood he was a passenger.
Police claimed Wiles allegedly "became aggressive and attempted to punch an officer". They also alleged he "resisted" and "kicked out" while being arrested.
Footage of the arrest, filmed by another person at the scene, shows two police officers allegedly pushing the man's face to the pavement and holding him in a headlock.
An officer allegedly appears to hit the man's face while he is lying on the pavement.
A female voice can be heard saying: "You didn't have to throw him like that."
Wiles was taken to Campbelltown Police Station on Friday, where he was charged with resisting an officer in the execution of duty, assaulting an officer in the execution of duty and breach of bail.
His girlfriend, Jayde Buggato, who is pregnant, claimed he was taking her to the doctors when he was arrested.
"I screamed. I said, 'You shouldn't be doing that,'" she said outside Parramatta Bail Court on Saturday, where Wiles was formally refused bail.
"That's dangerous, one hit could kill someone."
Wiles' mother Cheree Frank said they had an ongoing issue with one police officer in the area and will consider making an official complaint.
"I want all these coppers charged, the lot," she said outside court.
She said her son had "done nothing wrong in this case".
His father Peter Wiles said he was "pretty peed off", claiming it was not the first time his son has been "picked on" by police.
"They've actually smashed his kneecap once before," he alleged.
"We've got bone fragments at home from where his knee's been smashed in."
Mr Wiles admitted his son was "not a good kid" but said police shouldn't be allowed to dish out physical punishment.
"It's getting beyond a joke mate," he said. "We can't deal with it."
A spokeswoman for the police said no official complaints have been made yet against the officers involved in the arrest.
