A group of Lausanne-Sport hooligans attacked rival Thun fans during their Super League clash on Sunday.
Trouble erupted in the 71st minute when Lausanne-Sport hools invaded the running track at the Stade Olympique de la Pontaise and then attacked their Thun rivals.
Fighting between the two sets of rival fans forced the referee to abandon the game, which Lausanne-Sport were losing 2-0.
The troublemakers managed to leave the stadium without hindrance. Nevertheless, at least ten fans were later detained in different parts of Lausanne.
