FRANKFURT, Germany - Bayern Munich won 2-0 in Augsburg to extend its lead in the Bundesliga as defending champion Borussia Dortmund went down 3-2 with 10 men at home against Wolfsburg yesterday.

Dortmund and its 80,000 fans were left fuming at FIFA referee Wolfgang Stark, who sent off defender Marcel Schmelzer in the first half and awarded a penalty to Wolfsburg.

Goals from Thomas Mueller and Mario Gomez helped to lift Bayern 14 points ahead of Dortmund. Bayern is also 11 points ahead of Bayer Leverkusen, which plays tomorrow in Hannover.

Vedad Ibisevic scored a hat trick for Stuttgart to beat Schalke 3-1. Freiburg beat Greuther Fuerth 1-0 and Nuremberg blanked Fortuna Duesseldorf 2-0 in other matches.

Meanwhile, German football fans took their protest against proposed new stadium security rules to the streets in several cities ahead of Bundesliga and second division games.

Some 2,000 fans of Bundesliga champions Borussia Dortmund voiced their dissent in a march from the city centre to the stadium. Protests took place in Berlin, Augsburg and other cities.

The proposals for stricter security include searching fans at high-risk games, the elimination of already banned flares, and tougher sanctions against those who break the rules.

But fans are concerned that clubs ultimately aim to eliminate the popular German standing fan culture, though clubs have denied they want all-seater stadiums.

The protest, called 12/12, in reference to the league's deciding meeting on December 12, also calls for fans to remain silent for the first 12 minutes 12 seconds in three rounds of games, starting last weekend.
