Dmitry Rybolovlev, the owner of AS Monaco, was taken into police custody on Tuesday, the result of a probe into suspicions regarding bribery and corruption, according to reports.
The Ligue 1 club were one of the football outfits implicated in the damning Der Spiegel reports, with claims the owner attempted to circumvent Financial Fair Play (FFP) rules by using a bogus marketing deal to inject more funds into the club after Monaco incurred losses.
The report claims that the club agreed to a 10-year deal with Swiss-based marketing firm AIM four years ago that would see them earn more than £120m a season - a sum 10 times more than they had raked in the term prior.
