Real Madrid striker Karim Benzema has been charged over his admitted involvement in an alleged extortion case over a sex tape featuring fellow French international Mathieu Valbuena and appeared before a judge Thursday, legal sources said.

Benzema was charged with โ€œcomplicity in an attempt to blackmailโ€ and conspiring to commit a criminal act, which is punishable by at least five years in prison, the prosecutor's office in Versailles outside Paris said.

The 27-year-old star told investigators he approached Valbuena about the tape on behalf of โ€œa childhood friend.โ€ Benzema spent the night in custody after being arrested on Wednesday. A source close to the investigation said the player had admitted while he was in custody that he had spoken to Lyon midfielder Valbuena about the sex tape.
