WADA weightlifting probe finds evidence of doppelgangers providing samples

(Reuters) - A three-year investigation into the International Weightlifting Federation (IWF) has uncovered cases of suspected urine substitution and "doppelgangers" being used to impersonate athletes, the World Anti-Doping Agency (WADA) said on Thursday.

Eighteen weightlifters from six countries are suspected of giving manipulated samples, WADA said, adding that the cases of urine substitution would be forwarded to the International Testing Agency (ITA).
