Second Part of WADA Report on Alleged Doping Abuse in Russia Released

The second part of McLaren's report contains investigation materials comprising over 1,000 testimonies, including letters and results of tests.

The report claimed that more than 1,000 Russian athletes were involved in doping manipulations or benefitted from them.

"We are now able to confirm a cover up that dates back until at least 2011 and continued after the Sochi Olympic Games. It was a cover up that evolved from uncontrolled chaos to an institutionalised and disciplined medal-winning conspiracy," McLaren said at a news conference.

"It was a cover up an unprecedented scale and the second part of this report shows the evidence that increases the number of athletes involved as well as the scope of the conspiracy and cover up," McLaren said.

However, he welcomed recent Russia's reforms aimed at preventing doping.

He also claimed that the Russian Sports Ministry, the Russian Anti-doping agency (RUSADA) and the FSB were involved in covering up doping.

The report said that former Russian Sports Minister Vitaly Mutko and Deputy Minister Nagornykh were leading the process of testing methods of manipulating doping use.

The possibility of opening doping samples and mix-ups with DNA gives ground to assert that Russian athletes' doping samples were switched, the report said.

The report claimed that the concealment of doping use and other manipulations took place at four different sporting events, including 2 Olympic Games.

"This systematic and centralised cover up and manipulation of the doping control process evolved and was refined over the course of its use at London 2012 Summer Games, Universiade Games 2013, Moscow IAAF World Championships 2013, and the Winter Games in Sochi in 2014," the report said.

Doping samples of 12 out of 44 medalists, including 3 gold medalists, at Sochi Olympic Games were opened. The report said that 503 Russian athletes participating in summer games and 92 athletes participating in winter games were allegedly involved in doping manipulations.

"Over 1000 Russian athletes competing in summer, winter and Paralympic sport, can be identified as being involved in or benefiting from manipulations to conceal positive doping tests. Based on the information reported to International Federations through the IP to WADA there are 600 (84%) summer athletes and 95 (16%) winter athletes," the report read.

The report said that manipulations of Russian athletes' doping samples also took place after 2014 Sochi Olympics.

According to the newly-released report, doping samples of Russian athletes at 2014 Sochi Winter Olympic Games contain "impossible levels of salt."

"The … expert has confirmed that the salt levels in these two samples are physiologically impossible in a healthy human. Furthermore, DNA analysis of both samples revealed the presence of male DNA," the report read, referring to a particular case of a Russian female ice hockey player at the Sochi games.

Doping samples of 4 athletes from 2013 IAAF World Championship in Moscow were switched, the report said.

In July, a WADA commission led by McLaren presented a report based on the investigation results, in which Russia was accused of running a state-wide doping program, urging the International Olympic Committee (IOC) to consider a blanket ban on the entire Russian team. The IOC instead opted to let individual sports federations decide on the matter.

Following the report, Russian President Vladimir Putin vowed to suspend officials named in the report and stated that Russia would carry out an investigation of the allegations. The Russian leader also warned against politicizing sport and using it as a geopolitical tool.
