Five Russian weightlifters, all of them world or European championship medalists, face doping charges which could herald a new wave of cases across a range of sports.

The International Weightlifting Federation said Tuesday that evidence against the five athletes, including Olympic bronze medalist Ruslan Albegov, comes from new investigations by the World Anti-Doping Agency into widespread drug use in Russian sports.

“This important development shows justice being brought to those that may have cheated their sport,” WADA told The Associated Press in e-mailed comments on Tuesday.

“The Agency awaits more such announcements from federations that have commenced results management on the basis of evidentiary packages provided by WADA.”

IWF president Tamas Ajan said the alleged offences occurred “some years ago” and should be seen as part of efforts to clean up weightlifting, which was responsible for dozens of doping cases at recent Olympics.

“We have not shown any hesitation in taking the right decisions,” said Ajan, weightlifting’s leader since 2000, in a statement. “While the IWF has done so much to begin a bright new chapter for our sport, we will also do what we can to pursue historical cases of doping.”

Albegov is a two-time world champion who won bronze in July in a test event for next year’s Olympics in Tokyo.

The others are world champion Tima Turiyeva and double European champions Oleg Chen and David Bedzhanyan, as well as Egor Klimonov, who won European championship silver in April.

Russia was banned entirely from weightlifting at the 2016 Olympics when the IWF said its doping problem brought the sport into disrepute. For next year’s Olympics in Tokyo, Russia is among 17 countries hit with new doping-related restrictions on the size of their squads. (AP)
