American veteran Justin Gatlin was booed after he stunned Usain Bolt to win the 100m world title in London on Saturday.

Gatlin, who served a doping ban between 2006-10 and won silvers behind Bolt at the last two world championships, clocked 9.92 seconds, with teammate Christian Coleman winning silver in 9.94sec.

Bolt suffered a dreadful start and could only claim bronze in 9.95sec.
