PARIS, April 6 (Reuters) - Former Paris St Germain chairman Laurent Perpere has been placed under official investigation for using forged documents, the prosecutor's office said on Thursday.
Examining magistrates Renaud Van Ruymbeke and Francoise Desset have notified Perpere.
Perpere has denied any wrongdoing amid an inquiry over alleged under-the-counter payments made to players by Nike
In a statement at the time, Nike France denied the allegations and said this was purely French justice routine.
'This is a mechanical effect,' Nike said in the statement after three executives from the company had also been formally put under investigation.
'We are ready to cooperate with the authorities in this investigation even if we deny any wrongdoing,' the statement added.
Perpere was PSG chairman between 1998 and 2003, just before Francis Graille who was placed under investigation last month for the same reasons.
According to officials involved in the investigation, some 15 million euros (£9m) were moved from an account in Luxemburg through a Dutch subsidiary of Nike to PSG players and former coach Vahid Halilhodzic.
