A woman was thrown to the ground by a male police officer after chaos broke out in Liverpool city centre.
In a video of the melee two groups can be seen clashing at around 4am on Sunday morning.
At the start of the clip two men are being separated by five Merseyside Police officers, the Liverpool Echo reports.
One light grey t-shirt wearing man is pulled towards the road while a man in a black t-shirt is jostled the other way along the street.
As the men are in the grips of the officers, a blonde woman in a green dress is enters the fray.
A second woman, with darker hair and a dark green dress, suddenly grabs her hair from behind.
Three officers can be seen in the video jumping in to pull them apart.
However, seconds after the blonde woman is freed from her attacker's grasp, she is grabbed by a male officer who flings throw her over his outstretched leg, causing her to land heavily on the pavement.
The woman remains on the ground as the male officer and a female colleague stand over her.
The footage does not appear to show the woman struggling at the moment she was thrown to the ground.
It is not clear what started the incident or why police were called to the scene and it is not known whether the woman was injured during the fall.
Merseyside Police have been contacted for comment.
