Former Liverpool striker Djibril Cisse held over alleged blackmail plot involving fellow professional

Former Liverpool striker Djibril Cisse has been arrested as part of an investigation into a blackmail case that allegedly involves another football player.

Versailles prosecutor's office said in a statement that three other people were also taken into custody.

Cisse is accused of conspiracy to blackmail, a charge with a maximum prison sentence of five years.

A prosecutor's spokeswoman said the identity of the victim won't be revealed "out of respect for his/her private life".

The 34-year-old, whose career has been marred by injuries, is currently without a club. A former France international, Cisse scored nine goals in 41 games for his country.
