A race marshall died on Saturday after being hit by a motorbike at the Sepang circuit, weeks before the Malaysian MotoGP and two years after Italian Marco Simoncelli was killed.
Round three of the Malaysian Super Series Bikes was cancelled, according to a statement from the Sepang International Circuit (SIC), after marshall Satish Suppiah was killed during a practice session.
"Upon impact from the incident, the marshall was immediately treated on track by our medical team and later rushed to Putrajaya Hospital. Unfortunately, he succumbed to the serious injuries," it said.
SIC chief executive Razlan Razali told AFP the marshall was hit by a motorbike.
MotoGP rider Simoncelli died in a crash at the 2011 Malaysian Grand Prix. It prompted SIC to undertake a safety review of a track known to be notoriously tricky.
SIC said Saturday's incident was being investigated and a police report had been lodged.
The Malaysian MotoGP is on October 13.
