Elmer Funke Kupper has left his post at the Australian Securities Exchange amid a police inquiry into bribery allegations at a gambling company he previously headed.

Funke Kupper was the CEO of Tabcorp before he left the Australian wagering operator and took up the reigns as managing director and chief executive of Australia’s stock market in October 2011.

Tabcorp is currently embroiled in an ongoing investigation regarding a $200,000 payment that it reportedly made to the family of Cambodian prime minister Hun Sen.

According to local media outlets, Tabcorp deposited the money into a U.S. bank account by a consulting company linked to Hun Sen’s sister in 2010, which, incidentally, was also around the same time the wagering operator was pursuing an online sports betting license in Cambodia to boost the international profile of its then-new Luxbet online betting brand.
