English motorcyclist Daniel Hegarty has died after crashing against the barriers at the Macau Grand Prix.
The 31-year-old, who raced for Top Gun Honda, finished 16th on his debut at the street circuit last year.
The race organisers said: “Daniel’s family have been contacted, and the committee will ensure every assistance is extended to them.”
Northern Ireland’s Glenn Irwin was declared the winner after the event was stopped on the sixth lap.
A podium was held for the race without anthems or champagne and Irwin said it “was not a celebration”, adding: “It’s a very sad end to what has been a successful week.”
Hegarty died from his injuries as he was taken by ambulance to hospital.
The incident happened at Fishermen’s Bend on the 3.8-mile Guia Circuit.
Irwin, riding a PBM Ducati, had started from pole position but encountered mechanical problems in the early stages of the race.
However, he managed to keep pace with England’s Peter Hickman, winner of the past two years, and had manoeuvred himself into the lead by the time the race was red-flagged.
“I thought about pulling out but I was able to stay with the guys and was able to slow down into the corners,” added Irwin.
“The win is all irrelevant now and I wouldn’t have won the race had it gone the distance.
“It’s a tragic end to the day. That’s road racing and it’s tough.”
Macau, a resort city in southern China, has been hosting the street race for cars and motorbikes since 1954.
