Australia's Star Entertainment Group said on Monday its chief executive officer Matt Bekier had tendered his resignation, amid an investigation over possible breaches of anti-money laundering and counter-terrorism laws at its casinos.
The casino operator's shares, which have fallen over 12% already this year, were down as much as 1.9%.
Bekier informed the board that as managing director and CEO, he is "accountable for the effectiveness and adequacy of the company's processes, policies, people and culture," adding that the right thing to do was for him to take responsibility, a company statement said.
Bekier's decision to step down, effective immediately, followed issues raised at the public hearings in connection with the ongoing review of the Star Sydney hotel and casino, the company added in a statement. The Star Sydney is Australia's second largest casino.
The Australian Transaction Reports and Analysis Centre (AUSTRAC) had launched a probe in June last year into Star's casino in Sydney amid concerns over ongoing customer due diligence and compliance with laws.
