Two fresh doping cases have reportedly hit the 2014 Winter Olympics in Sochi which took the total number of failed drugs tests to four.
The latest cases come after German biathlete Evi Sachenbacher-Stehle and Italian bobsledder William Frullani were expelled from the Olympics for testing positive for banned substances.
According to the Sydney Morning Herald, the Ukrainian Olympic Committee stated that cross country skier Marina Lisogor had tested positive for a banned substance while the International Olympic Committee (IOC) later confirmed it had sanctioned Latvian men's ice hockey player Vitalijs Pavlovs.
The report mentioned that Pavlovs had tested positive on February 19 for the banned substance methylhexaneamine and has been kicked out of the Games, while Lisogor admitted that she had unwittingly consumed the banned trimetazidine in a medicine.
Trimetazidine, which was included on the banned list from January 1, 2014, improves glucose utilization, the report further said.
Meanwhile, a senior German Olympic official said that his country's prosecutors had conducted searches in Ruhpolding, the Bavarian base of the German biathlon team, and at the home of Sachenbacher-Stehle.
