Federal prosecutors in the German city of Bochum are investigating match fixing allegations of over 200 football matches in nine European countries including at least three Champions League games German prosecutors said on Friday. They revealed that more than 30 of the matches under investigation took place in Germany, and that two named Croatians have already been arrested. The arrests which took place on Thursday included brothers, Ante and Milan Sapina, who were at the center of a previous match-fixing scandal in Germany in 2004. That case saw referee Robert Hoyzer sentenced to two years and five months in prison after he admitted to accepting bribes to manipulate games. However a further 13 people have also been arrested in Germany and two more in neighbouring Switzerland are also under arrest. A series of around 50 raids were carried out on Thursday in four countries, during which documents, around $1 million in cash and valuables were seized. As well as Germany and Switzerland, police in England and Austria are believed to have been involved.
