The FIA have launched an investigation of a highly-sensitive nature regarding a previous Formula One race result.
It is understood motor sport's world governing body are looking into the events of last season's inaugural Singapore Grand Prix.
The race, which made history as it was the first night event run under floodlights, was won by Renault's double world champion Fernando Alonso.
During the race Alonso's then team-mate Nelson Piquet, who was axed by the French manufacturer last month following a string of poor results, crashed on lap 14, bringing out the safety car.
The FIA refused to specifically divulge either the race concerned or the circumstances that have resulted in them making their enquiries, though it has been suggested they are enquiring into the possibility that the crash was caused deliberately in order to aid the progress of Alonso, who went on to win the race.
Following the Belgian Grand Prix an FIA spokesperson simply stated: "The FIA can confirm that an investigation is under way regarding alleged events at a previous world championship race."
