Referee Robert Hoyzer, the official at the heart of Germany’s major match-fixing scandal, could remain in prison on “investigative custody” for up to three months, the Berlin prosecutors’ office has confirmed.

“He is entitled to a re-examination of his imprisonment only after spending three months in investigative custody,” said Michael Grunwald, spokesman for the state prosecutors’ office.

Hoyzer was arrested on February 11 after being accused of match-fixing.

He faces a possible custodial sentence of up to 10 years if convicted on charges of involvement in organised criminal activity.
