Police stated that the razzia was a preventative measure on short notice to prevent hooligans from organizing for the upcoming match against 1. FC Union Berlin on 21 August 2005. There were speculations that police also took revenge for riots during the match between BFC Dynamo and SV Yeşilyurt at the opening of the season, when supporters of BFC Dynamo had attacked the police with 13 police officers injured. More than 1,000 police offiers were deployed to the derby and the match was played without crowd trouble. The second match between BFC Dynamo and 1. FC Union in the 2005–06 NOFV-Oberliga season was played at the Stadion im Sportforum on 13 May 2006. The standing was 1-1 when supporters of BFC Dynamo invaded the pitch in an attempt to storm the block of 1. FC Union Berlin around the 75th minute. The match was abandoned and 1. FC Union Berlin was awarded a 2–0 win.
