Sochi: An Austrian cross country skier was thrown out of the Sochi Olympics and labelled a "scoundrel" by his own team Sunday after testing positive for blood booster EPO -- the fifth doping case to hit the Games.

Johannes Duerr, who had been due to take part in the men's 50km on the final day of the Games, tested positive in a pre-competition test in Austria on February 16, organisers said in a statement.
