Vienna state prosecution on Wednesday confirmed Austrian media reports, saying the investigation started last year after the four women filed charges against their former coach. If charged and found guilty, the 54-year-old Seisenbacher could face a prison term of up to 10 years. Seisenbacher became the first judoka to win gold at two consecutive Olympics, in 1984 in Los Angeles and four years later in Seoul. Seisenbacher was head coach of the Georgia team when Lasha Shavdatuashvili won gold in the men's 66-kilogram division at the 2012 London Olympics.
