German police on Wednesday arrested referee Dominik Marks on suspicion of fraud for fixing three soccer matches in late 2004, prosecutors said on Thursday, according to Reuters news service. Marks, 29, was arrested at his Berlin apartment based on "credible information provided by (fellow referee) Robert Hoyzer that was supported by other objective evidence." Hoyzer himself is the main suspect in the worst match-fixing scandal to hit German soccer in more than 30 years. The 25-year-old is cooperating with prosecutors after he admitted that he fixed matches for money. Hoyzer was arrested in February, but released two weeks later. He now faces eight charges of complicity to defraud.
