A leading Indian woman weightlifter has pulled out of a pre-Olympic training camp after testing positive for the banned steroid nandrolone at the Asian championships last month.

S.Sunaina, 24, will be stripped of the 58 kg bronze medal she won in Almaty, Kazakhstan, and banned for two years if her second, or B sample, is also positive.

"We received the report from the Asian body yesterday that she has returned a positive test," Balbir Bhatia, secretary of the Indian Weightlifting Federation, told Reuters.

Sunaina was also a bronze medallist at the 2002 Manchester Commonwealth Games.

Bhatia said the Indian federation was concerned over the latest in a series of doping offences by Indian lifters.

Last year, Commonwealth Games 75 kg gold medallist Shailaja Pujari was banned for two years by the Indian federation after she tested positive at a domestic meeting.

She was among 34 lifters, 23 of them juniors, who were caught for doping in three national meets which came soon after seven lifters tested positive during the 2002 national games.
