Speaking outside the Hastings court early this afternoon, having missed her son's appearance which had been held several hours earlier, Kiri Turner said the police need to be accountable for what she in says was excessive force.
"They can't be allowed to get away with it," she said, fearing that nothing would be done.
She said as with the incident her son had witnessed when the family was stopped on the Desert Rd several years ago children should not have been subjected to what they saw last night. "It's not fair," she said.
She said police approached her son, he asked to be able to get something from the car, and they struggled with him and threw him to the ground.
She was catching-up with her son at home in Napier later this afternoon, and hoping to see a lawyer and then make a complaint.
In their statement police said they stopped the car at KFC in Napier to arrest a man who was wanted on a warrant, and had been banned from driving. The car was also to be impounded.
He was "uncooperative with police", and refused to get out of the car, police said.
"When he did, he became aggressive and resisted all attempts to handcuff him," the statement said.
"He struggled violently with police, who used pepper spray on him.
"The spray hit the man but also splashed back into the face of one officer, making him incapable of assisting any further.
"Despite the pepper spray, the man continued to struggle violently and refused to be handcuffed.
"His head was pushed to the ground by one officer in a bid to stop him struggling."
When police attempted to get the car keys out of the car, the man's mother, girlfriend and sister "became obstructive", police said, and refused to let officers into the car.
"They became abusive and violent and also resisted arrest."
