The fire early last Friday morning caused extensive damage to the offices and destroyed team memorabilia.It was the most violent event in more than two weeks of incidents between fanatic Beitar supporters angry at Beitar management for signing two Muslim players. Police arrested more than 25 people for throwing rocks at players’ cards, harassing and attacking team security guards, and protesting outside of practices. Jerusalem police spokesman Shmuel Ben Ruby said the four men arrested Tuesday night identified themselves as members of La Familia, a hard-core group of Beitar fans known for chanting “death to Arabs!” at matches. The men are from the center of the country.The men are currently undergoing questioning in Jerusalem. Ben Ruby said he expects the police to make additional arrests in connection with the arson.On Wednesday, Beitar midfielder Ofir Kriaf was suspended by the club until Monday after showing support for the La Familia fan club on his Facebook page. Kriaf will miss Sunday's match at Hapoel Haifa.The Israel Football Association's disciplinary court also turned down Beitar's appeal on Wednesday against the closure of the East stand at Teddy Stadium for five matches.The IFA court handed Beitar the punishment after fans raised a banner reading "Beitar Pure Forever" and sang anti-Arab chants during the 1-0 defeat to Bnei Yehuda on January 26, The eastern stand is traditionally the place where fans from La Familia sit.Fans weren't allowed to enter the eastern stand for Sunday's match against Bnei Sakhnin and it will remain shut for the team's next four homes games. Instead, the team covered the empty stand with giant posters decrying recent events. “Violence and racism? Not on our fields!” read one at the recent game against Bnei Sakhnin.Public security minister Yitzhak Aharovitch is scheduled to meet with the management of soccer teams on Thursday in order to discuss the recent spate of violence in soccer.
