After years of circulating rumors, in June 2014 a number of women filed criminal complaints against Seisenbacher for alleged sexual misconduct against them when they were still minors.

[4][5][6][7] The formal indictment came after a lengthy judicial investigation following earlier police complaints filed in 2013 by several former pupils, as reported by numerous newspapers in June 2014.

[8][9][10] However, in December 2016 Seisenbacher failed to show up for his trial in court for two days in a row and instead fled the country, after which he officially became a fugitive from justice on worldwide warrant.

[11] [12][13] While Interpol searched for him in Europe, Kazachstan, the United States and Dubai,[11] Seisenbacher was able to remain on the run for 200 days.

Considered dangerous, he was finally arrested by a SWAT team on 2 August 2017 in Kyiv, Ukraine and was handed over to Austria on 12 September 2019.
