The Police Integrity Commission will investigate the alleged assault of former local man, 21-year-old Corey Barker, by up to five police officers at Ballina police station in January last year.
The investigation could lead to contempt of court charges against three police officers, constable Walmsley and senior constables Hill and Eckersley, who would then face the Supreme Court.
Echonetdaily understands the officers remain on duty despite the investigation.
Local media reports that Mr Barker attempted to break up an argument between two friends but police moved in and threw one of them to the ground.
When Mr Barker began filming the incident on his mobile phone, he was arrested and taken to Ballina police station where the alleged assault occurred.
CCTV evidence allegedly shows five police officers attacking Mr Barker, including punching him, throwing him to the ground, kicking him and stomping on his hand.
The police prosecutor told the court that Mr Barker had thrown the first punch off camera but Magistrate Heilpern found no evidence that he did.
The judge described the officers as ‘contemptuous’ and said they had given ‘palpably false evidence’.
‘I am satisfied on balance that the officer has lied on oath about this issue in an effort to mislead the court,’ APN Media reported.
Costs were awarded against the police.
