A police officer has been removed from frontline duties after a video showed a man being told "chill out or I'll choke you out" during an arrest.
West Yorkshire Police said the matter has been referred to the police watchdog after footage emerged of the incident in Halifax.
The 45-second clip shows two male uniformed officers grappling on a pavement with a man wearing shorts and a T-shirt.
One of the officers appears to say to him "chill out or I'll choke you out" and then "chill out or you're going to sleep".
The officers manage to get the man onto his front and one tries to handcuff him as the other appears to be talking on his radio.
Temporary Assistant Chief Constable Osman Khan confirmed the video showed the arrest of a man at Spring Hall Gardens in Halifax on Sunday "in relation to assault offences".
"We immediately reviewed the footage and looked into it as a matter of urgency to establish the full circumstances," he added.
