Real Madrid striker Karim Benzema has been arrested over an alleged plot to blackmail fellow footballer Mathieu Valbuena with a sex tape, legal sources have said, reports.

The Real Madrid and France star arrived at the police station in Versailles, near Paris, early on Wednesday and was placed in detention, the local prosecutor confirmed, without giving further information.

The case also saw four other people arrested last month, including former French international footballer Disséjibril C.

Cissé took to live television the day after his arrest to insist that he was innocent.

The existence of any x-rated video involving Lyon player Valbuena and his partner, however, has not actually been confirmed.
