Once again, traveling fans provoked riots in Super League games this weekend, now that the ban on away teams getting tickets has been lifted. Panathinaikos supporters burned a police car during clashes with officers in Kavala, while Olympiakos fans caused extensive damage at Serres. Upset about the loss of two points by their team, Panathinaikos fans started hurling objects at the police officers inside the Kavala stadium on Saturday night, as well as at those outside. Police responded by firing tear gas and the clashes continued for a long time outside the stadium, with one police car getting torched and police arresting one suspected hooligan. There were some 4,000 Panathinaikos fans at the Anthi Karagianni Stadium on Saturday but only a handful are believed to have provoked the riots. Yesterday dozens of Olympiakos fans were roaming the northern city of Serres, home to Panserraikos. Some vandalized shops and cars, while their main focus was a PAOK fan club in the city. A police intervention contained the riots, while one man who suffered injuries was treated on the spot.
