Real Madrid striker Karim Benzema was held in custody on Wednesday in connection with blackmail over a sextape featuring fellow French player Mathieu Valbuena, report the AFP news agency.
According to the legal sources, 27-year-old Benzema mentioned the sextape to Valbuena while at a training camp for the French national team.
French investigators are examining whether Benzema was teasing Valbuena or if it was used as blackmail by the suspects.

Three suspected blackmailers were charged and held in custody in October. The case was open in July and carries a potential prison sentence of five years.
The French striker is said to be staying overnight in custody.
