The case comes after Austrian police arrested five skiers, two of them Estonians, at the Nordic skiing world championships. Another Estonian skier, three-time Olympian Algo Karp, told the Ohtuleht newspaper that he also doped.
The case has caused a scandal in Estonia, where cross-country skiers are star athletes responsible for all of the small Baltic nation's seven Winter Olympic medals. Alaver was stripped of two state honors by President Kersti Kaljulaid last week after he was first linked to the Austrian arrests.
