Massive fights and public disorders between Ultras Sur (Real Madrid CF, right-wing) and Bukaneros (Rayo Vallecano, left-wing), both teams from Madrid. The local group, US, patrolled their stadium and territory all the day. Police caught a large group of them. Three hours before the match Bukaneros appeared from nowhere and assaulted the pub of the local group with bigger numbers, so upper hand for the visitors and a truly surprising victory. Very well played. Then police appeared and restored the order. After the match, massive fight again after the US attack against the police escort of the visitors.
Bukaneros got 75 members retained, US also have some identificeds. Probably, according to the spanish "traditions", all of them will be banned and fined. Fines between 3.000 and 60.000 euros, I guess. Strength for all of them!
