Chaos unfolded in the stands prior to AEK Athens’ Champions League clash with Ajax in Greece.
Riot police were called into action to diffuse the situation after home supporters threw a petrol bomb and flares into the stands where the travelling Ajax fans were.
But shocking photos show the officers whacking the Dutch supporters with batons, leaving individuals with gruesome cuts.
One picture shows an Ajax fan reacting towards a police officer as he sports a bloodied face as a result of the violence.
While another shows an AEK Athens throwing a flare into the crowd as riot police simply look on.
Reports have suggested that Panathinaikos fans were among the travelling supporters, with the Greens and AEK sharing a fierce rivalry.
One supporter at the ground tweeted: “Riots in Athens. AEK fans attack Ajax box with fireworks because there are fans of Panathinaikos between the Amsterdammers.”
Ajax defender Matthijs de Ligt – a target for Manchester United, Manchester City and Barcelona – ran over to the Ajax fans as he looked to play peacemaker.
AEK currently sit bottom of Group E having lost their opening four games, and have failed to advance to the knockout stages.
While Ajax are on the brink of sealing their place in the last-16 having picked up two wins and two draws.
