WARSAW: Jamaican sprint superstar Usain Bolt has set a best time of 9.98 seconds for the rarely run 100 metres indoors, at Warsaw's national football stadium.

The Olympic champion and world record holder (9.58s) on Saturday eclipsed the previous best mark for the distance of 10.05 set by Namibian Frankie Fredericks in 1996.

Bolt, in action as preparation for Zurich's Diamond League meeting next week, said: "Above all I wanted to get through this season without any injury as I've suffered enough over the past few years.
