Usain Bolt of Jamaica made history on Thursday when he won the Olympic 200m crown to claim an unprecedented second successive sprint double. He had won gold in both 100m and 200m at Beijing Olympics also.
Bolt who won the Gold in 100m on Saturday , won the 200m with a time of 19.32sec in front of an 80,000 crowd at the Olympic Stadium.
The 25-year-old bettered the record of US track legend Carl Lewis, who won three golds and a silver in the sprints at the 1984 and 1988 Games.
It was also the first time two individual track titles were successfully defended at successive Games since Finland’s Lasse Viren won the 5000m and 10,000m in the Munich and Montreal Games in 1972 and 1976.
Bolt led a Jamaican clean sweep of the race, with training partner Yohan Blake taking silver in 19.44sec and Warren Weir claiming bronze in 19.84sec.
