Belarusian shot putter Nadzeya Ostapchuk who was stripped of her Olympic Champion title has been caught doping again.
The finding relates to Ostapchuk's 2005 world shot put title in Helsinki, Finland.
The International Association of Athletics Federations (IAAF) re-tested a selection of samples collected from athletes in a range of sports and countries competing, which revealed six failed results.
Fellow Belarusian athletes Andrei Mikhnevich, Ivan Tsikhan and Vadim Devyatovskiy, along with Russians Tatyana Kotova, and Olga Kuzenkova were also found guilty of doping in the re-test.
Ostapchuk briefly was stripped of her Olympic gold medal last year for failing a drug test. The medal was awarded to New Zealand's Valerie Adams.
"It is fantastic that the IAAF are working hard to uncover drug cheats and are focused on maintaining the integrity of the sport," said Adams said in a statement today.
