Olympiacos hooligans clashed with riot police on the pitch at the Karaiskakis Stadium after their side’s 3-1 defeat to AEK on Sunday.
Just after the final whistle, a large group of Olympiacos hooligans ran onto the pitch, throwing bottles and other objects at players and officials racing into the tunnel.
Riot police attempted to restore order, but the outraged pitch invaders immediately turned on them, throwing various missiles.
Olympiacos are currently third in the Greek Super League table and nine points away from the top.
