RIO DE JANEIRO (AFP) - Thailand's Sukanya Srisurat, who previously served a two-year ban for doping, pipped compatriot Pimsiri Sirikaew to gold in the women's 58kg weightlifting competition at the Rio Olympics on Monday.

Sukanya lifted an Olympic record 110kg in the snatch and 130kg in the clean and jerk for a total of 240kg, beating the silver medallist by 8kg.

The International Weightlifting Federation banned Sukanya from the sport from May 2011 to May 2013 after she tested positive as a 16-year-old for the prohibited substance methandienone, an anabolic steroid.

Pimsiri, 26, lifted 102kg in the snatch and jerked 130 for her total of 232kg to add another silver medal to the one she won at London four years ago.

Kuo Hsing-chun claimed bronze for Taiwan with her combined total of 231.

Thailand have dominated the opening days of the weightlifting with four medals, grabbing two golds and a silver in the women's competition and a bronze in the men's so far.
