The four men, charged with inflicting bodily harm, torture and breaking anti-racist laws, were brought before a prosecutor on Saturday night after an investigation led by Athens’ police internal affairs unit.
They were released pending their trial.
A video aired on social media shows four men beating two asylum-seekers in the camp on the Aegean island as they were returned from a super market on Friday.
The policemen keep beating them even after handcuffing.
On Friday night, the police announced an investigation on the matter.
Police sources said the four men claimed they hit the asylum-seekers because they were attacking passing cars and drunk.
The asylum-seekers have returned to Kara Tepe camp which houses 7,300 migrants, including vulnerable groups, in harsh conditions.
