The national record for the 100m event which was held by Watson Nyambek for 17 years was broken by Badrul Hisham Abdul Manap on the first day of the Asean Schools meet in Brunei, on Monday.

The 18-year-old Melaka-born athlete, who was the defending champion in the event, recorded a time of 10.29 seconds to demolish Watson's record of 10.30 seconds which was set at the Malaysian Open Athletics Championship in 1998.

Second place went to another national athlete, Asnawi Hashim who clocked 10.71s while Worawutsalabal of Thailand finished in 10.87s to claim third spot at the Tutong Sport Complex, according to the official website asg7.moe.gov.bn.

Earlier, Malaysia added two gold medals from swimming to keep pace with leader Indonesia with five gold medals, three silver and one bronze medal.

Indonesia reigned supreme on the first day with seven gold medals, six silver medals and one bronze while Vietnam was third with four gold, one silver and three bronze medals.

For the record, Malaysia emerged overall champions in the annual sporting event in 2010 which was held here and last year in the Philippines.
