During the video, a voice can be heard saying "chill out or I'll choke you out, chill out or you're going to sleep".
The officer involved has been suspended by West Yorkshire Police pending an investigation and the matter has been referred to the Independent Office for Police Conduct (IOPC).
In a statement, the IOPC said it would be investigating the incident.
IOPC Regional Director Miranda Biddle said: “We can understand why the images circulated have caused considerable public concern and we would like to reassure members of the community that we have taken the decision to independently investigate this incident after West Yorkshire Police made a voluntary referral to us.
“An investigation has now commenced to ensure that we are able to fully understand what happened. It is vital that we are able to impartially determine the facts.
“We have already begun to gather evidence but we would like to speak to anyone who was in Spring Hill Lane in Halifax at around 15:00 on Sunday who may have witnessed this incident.”
