North Wales Police are to review video footage which appears to show an officer kicking a football fan on the floor at a match in Wrexham.
Three fans were arrested at the Blue Square Bet Premier game where Wrexham beat Newport one nil on Saturday.
The video, posted on the social media site You Tube, shows the officer kicking the fan twice in the back.
The force said three officers were injured – one with a broken wrist – after trouble flared.
The You Tube clip shows police with batons drawn at the rear of a bus from south Wales.
One officer appears to kick a fan twice as he lies on the floor. The fan is then dragged away.
A North Wales Police spokesman said: “We are aware of the video and will be reviewing the footage.
“Three people were arrested at the game on Sunday, two from Newport. One who has been charged with a public order offence and assaulting police, and has been bailed to appear before court.
“The other was given a caution for obstructing a constable.
“A Wrexham fan was also arrested and charged with a public order offence and has been bailed to appear before court.”
