Lausanne: The Court of Arbitration for Sport (CAS) has announced stripping Russian boxer Misha Aloian of his 2016 Rio Olympics medal for anti-doping violations.

"Russian boxer Misha Aloian is found to have committed an anti-doping rule violation after testing positive for Tuaminoheptane, a specified stimulant, prohibited in-competition under S6 on the WADA Prohibited List, during an in-competition doping control on 21 August 2016," CAS said in a statement Thursday.

"The results obtained by the athlete in the Rio 2016 Olympic Games, including the silver medal obtained in the men's 52 kilogram boxing event on 21 August 2016, are disqualified," the statement read.

Aloian was among the athletes, mentioned in confidential documents stolen from a Rio 2016 Olympic Games account of World Anti-Doping Agency (WADA) Anti-Doping Administration and Management System (ADAMS) and published by hacking group called Fancy Bears.

The documents confirmed that the WADA authorised the use of doping by 127 athletes from different countries, who had a therapeutic permission. The list includes medallists of the Olympic Games in Rio, including Aloian, who is also a two-time world champion and the bronze medallist of the 2012 Olympic Games in London.

The boxer earlier explained that the banned substance was found in nasal drops that he had to use.

His coach Eduard Kravtsov said the athlete will file an appeal against the CAS decision.

"We have considered this variant, a lawyer was ready for this. We will keep pursuing this matter in courts and are not going to abandon it," he said on Thursday.
