Canadian sprinter tests positive for steroidThe World Championships hosted by Canada turned out to be an embarrassment after one of their 100m sprinters tested positive for an anabolic steroid.

Venolyn Clarke, who finished eighth in her quarter-final heat, was found to have been tested positive for stanozolol – the same drug that brought an abrupt end to the illustrious career of Ben Johnson after he had won the Olympic 100m final in Seoul in 1998.

Clarke now faces a four-year ban from competition.
