World Athletics: Usain Bolt disqualified from 100m final

Usain Bolt is dramatically disqualified after false-starting in the final of the 100m at the 2011 World Athletics Championships in Daegu.

The Jamaican was hoping to defend the gold he won in Berlin in 2009, but was shown a red card for jumping the gun as compatriot Yohan Blake took the victory.

Bolt will be looking to win his second 100m world title in at the 2013 World Athletics Championships in Moscow.
