Turkmenistan's Tejen Tejenov yesterday became the first medalist at the Hangzhou Asian Games to fail a doping test as the number of doping cases mounts.
The 30-year-old, who came second in the heavyweight 90kg category of kurash, an ancient form of wrestling, tested positive for anabolic steroids, the International Testing Agency said.
He has been provisionally suspended and is in danger of being stripped of his silver medal.
"He has the right to request the analysis of the B-sample," said the ITA, which handles some areas of doping control at the Games.
Tejenov won silver behind Uzbek winner Mukhsin Khismomiddinov on September 30 and was tested the same day.
Doping results generally take several days to come through.
Uzbek cyclist Aleksey Fomovskiy, Philippine mountain-bike rider Ariana Evangelista, Saudi distance runner Mohammed Yousef Alasiri and Afghan boxer Mohammad Khaibar Nooristani have also failed drugs tests in Hangzhou.
They have also been provisionally suspended.
The Games end on Sunday.
Meanwhile, China's He Jie clinched the marathon title, with Bahraini Eunice Chumba winning the women's race.
He, who came 45th at the August world championships in Budapest, was neck-and-neck with North Korea's Han Ilryong at the 40-kilometer mark before edging clear to finish in two hours, 13 minutes, two seconds.
In cycling, young Kazakh rider Yevgeniy Fedorov was gifted gold by decorated teammate Alexey Lutsenko as they crossed the line nearly six minutes ahead of the rest in the men's road race.
