Russian Premier League team Torpedo Moscow must play two home games in an empty stadium after fans displayed a banner with a Nazi symbol, the club's fourth racism-related punishment this season. Torpedo supporters showed the flag during the club's 3-1 win over Arsenal Tula on Sunday. The punishment will not take effect until May because Torpedo are already required to play their next two home games behind closed doors for a separate incident in which fans abused Zenit St Petersburg striker Hulk with monkey chants. Sunday's clash between Torpedo Moscow and Arsenal Tula was marred by violence and racism . A fan lays on the ground after being attacked by rival supporters during Torpedo's latest away game .

For that, Torpedo fans will be barred from the club's next three away games, with the exception of women and children under 13. Torpedo was fined a total of 900,000 rubles (£11,000) for various offenses including the Nazi banner, the fighting, use of pyrotechnics by fans, and insulting chants. Arsenal received a 480,000-ruble (£6,000) fine on charges including failing to secure the stadium properly. Police detained 15 fans at the game, of which seven face charges, Russian agency Tass reported on Monday. In response to the incidents at Sunday's game, Torpedo president Alexander Tukmanov told the R-Sport agency that the club's fans seemed to be 'probably the most aggressive' of any top-flight Russian team. Torpedo's previous three racism offenses this season all involved monkey chants against opposition players. Torpedo are already due to play their next two home games behind closed doors after aiming monkey chants at Zenit St Petersburg during their fixture last month .

Separately on Tuesday, Zenit coach Andre Villas-Boas was given a suspended one-game ban by the Russian Football Union for repeatedly breaking rules on leaving his technical area at games throughout the season.
