It appears the Moscow Laboratory operated the doping ring and the Sochi lab swapped samples all under the eye of the Russian Ministry of Sport oversaw the process, with participation from the Russian security service.
The executive board of the International Olympic Committee (IOC) will convene on Tuesday to discuss the possibility of imposing "provisional measures and sanctions" on Russian Federation relating to next month's Rio Games, following the publication of a damning report by Professor Richard McLaren.
Although, McLaren does claim that at least one foreign footballer playing in the Russian Premier League had a positive drugs sample swapped for a negative one in the Moscow lab, as ordered by Russian Sports Minister Vitaly Mutko.
U.S. Olympic Committee CEO Scott Blackmun said the report proved a point he had made earlier this summer - that the current anti-doping system is broken.
The Russian weightlifting team is also facing the prospect of a ban from Rio after repeated anti-doping violations.
McLaren's report primarily looked into allegations made by the former head of Russia's national anti-doping laboratory - Grigory Rodchenkov.
"This campaign is apparently based on information received by the WADA commission led by Canadian lawyer Richard McLaren, though this report should remain independent and completely confidential until the date of its release".
The statement said the International Olympic Committee executive board would hold a conference call to discuss immediate sanctions surrounding the Rio Olympics.
A damning report compiled by a Western University law professor that confirms there was state-sponsored doping is adding to the push for Russian Federation to be banned from the Rio Olympics. The track and field team was subsequently banned from competing in Rio in June.
According to the report, the Russian Ministry of Sport erased at least 312 positive doping tests between 2011 and 2015.
- The report made no recommendations for sanctions or discipline against Russian Federation. Some medal winners were involved in doping at the Sochi Games, the report's chief investigator Martin Dubbey said during the news conference.
"The IOC will not hesitate to take the toughest sanctions available against any individual or organization implicated", IOC President Thomas Bach said.
"FIG is concerned about the increasing number of officials asking for a blanket ban of Russian athletes to participate at the forthcoming Olympic Games in Rio", the sport's governing body said in a statement.
"In the face of such evidence of state-sponsored subversion of anti-doping processes, WADA insists upon imposition of the most serious consequences to protect clean athletes from the scourge of doping in sport", said WADA president Craig Reedie, who is also an International Olympic Committee member.
"The IPC will now analyse the report's findings in detail to evaluate what impact they have on the Paralympic Movement and Para Sport".
