New South Wales Police said they are investigating accusations of racial abuse levelled against a police officer who was filmed during a traffic stop in the northwestern Sydney suburb of Carlingford.
At 6.30am on Christmas Day, the officer pulled a driver in his car aside and asked him where he was from. The video also captures him appearing to tell the driver: 'go back to China'.
Calib Strik filmed the incident on his phone, posting the exchange on his Facebook page.
He said it was a "shame" to witness such "an appalling manner".
"Sad to see this particular police officer (highway patrol) use his power and position in such an appalling manner," he wrote on social media.
"Such a shame to witness racism and abuse to a driver who had no idea what his rights where."
Mr Strik confronts the police officer in another video, accusing him of racial abuse.

The officer responds by requesting Mr Strik stop "harassing" him.
A spokesperson for NSW Police said a review is underway.
"Police are aware of the video and are making enquiries."
As part of the investigation procedure, the police officer's body camera footage could be subject to examination, with the outcome potentially resulting in a professional standards review.
