Nadzeya Ostapchuk has been caught doping again.

The Belarussian shotputter, who infamously denied Dame Valerie Adams victory at the London 2012 Olympics before being found days later to have doped, will have to give back her 2008 bronze from Beijing.

A sample taken from the games has shown the presence of two banned substances in her system upon retesting.

Adams is now the only medal winner left standing from the 2008 Olympic women's shotput.

It comes in the wake of a fresh wave of positive results on re-testing of Beijing and London samples, with two female weightlifting gold medallists stripped of their Beijing results in the latest batch.
