A schoolboy was still being treated in hospital last night and another two were discharged after being seriously injured by a mob of some 50 soccer hooligans wielding iron bars and screwdrivers, following the top of the league clash between crosstown rivals Panathinaikos and Olympiakos hours earlier. The three teenagers, two of whom were named as brothers Giorgos and Dimitris Fellas, were attacked just after midnight in the western suburb of Peristeri after the mob spotted one of them wearing a Panathinaikos T-shirt. Police believe the attackers were Olympiakos supporters. No arrests were made, as the gang made off on motorcycles after the incident. Panathinaikos won the home tie against its bitter rivals by 1-0 to go clear to the top of the first division. Although no Olympiakos fans were allowed to attend the game, there were some disturbances at the ground as 200 fans without tickets forced their way into the stadium in central Athens. They had earlier clashed with riot police outside, throwing firebombs and damaging several parked cars.
