The corruption trial involving the former president of track and field’s governing body was suspended Monday shortly after it began.

Lamine Diack, the former head of the IAAF, has been charged with far-reaching corruption and doping cover-ups.

At the opening of the hearing, the prosecution asked that the two-week trial be delayed to weigh new evidence received from Senegal, where Diack was born. His son, Papa Massata Diack, also charged in the case, lives in Senegal, shielded from an international arrest warrant issued by France.

The prosecution also asked for the delay to clear up a procedural technicality regarding one of the charges against Papa Massata Diack. There will next be a hearing in April to see whether a new trial date in June is feasible.

Addressing the court, the 86-year-old Diack asked that in the wake of the delay he be allowed to travel to Senegal to visit his elder brother, who recently celebrated his 100th birthday. Diack has not been allowed to leave France since his arrest in 2015. But he promised the court that he would come back to France if allowed to travel, saying he wants to clear his name.
