The match between AEK Athens and Atromitos at the OAKA stadium had to be ended early after hooligans poured onto the pitch and was marred by violence both before and after the game, when supporters of AEK and Panathinaikos came to blows.
Police reported that at 5:10 on Saturday a large number of AEK supporters attacked police stationed at at the corner of Alexandras Avenue and Harilaou Trikoupi street in Athens with petrol bombs, flares and stones in an attempt to reach a Panathinaikos supporters' clubhouse nearby. Earlier, AEK and PAO supporters had exchanged verbal insults as the former passed the clubhouse.
A second group of AEK supporters on mopeds and motorbikes coming from the direction of Zografou also vandalised two police patrol cars and other parked cars, the PAO clubhouse and clashed with a small group of PAO supporters that were there at the time.
At 7:00 p.m. there followed an attack by PAO supporters on two coaches carrying AEK supporters to the game as they drove up Alexandras Avenue, while they also attacked a police platoon that moved in to protect the coaches.
