Former Liverpool and France striker Djibril Cisse is one of four people held by police over an alleged attempt to blackmail an international footballer.
The former Sunderland and QPR forward who has been arrested over a sex tape extortion plot was reportedly questioned because he knew the others involved in the attempted extortion involved video footage of sex that had been recorded on a mobile phone.
Cisse who spent three years at Liverpool was taken into custody by Versailles police at 06:00 local time on Tuesday. This follows an investigation into blackmail and conspiracy to commit an offence that was opened on 31 July 2015.
According to BBC Sports, French prosecutors say Cisse was not thought to be an instigator of the conspiracy – an offence which carries a minimum five-year sentence.
The alleged victim has not been identified by the authorities “out of respect for their private life”, reported Associated Press news agency.
Cisse joined Liverpool in 2004 and scored 24 goals in 79 appearances for the Merseyside club before leaving in 2007.
He then returned to the Premier League with Sunderland in 2008, netting 11 goals during a season-long loan, before joining QPR in January 2012, for whom he scored 10 goals in an 18-month spell.
Cisse, who was released by Ligue 1 side Bastia in the summer, also scored nine times for France in 41 appearances.
