Shares of WiseTech Global plunged 11% after Australian federal police launched an investigation into co-founder Richard White over allegations of sex exploitation. The probe, reported by the Sydney Morning Herald, centers on claims that White exploited a woman's immigration status.

The investigation adds to a turbulent year for the logistics software firm. White, a billionaire entrepreneur, has been the subject of multiple controversies that have weighed on investor confidence.

WiseTech's stock has fallen approximately 67% over the past year. The latest decline compounds ongoing losses that have significantly reduced the company's market valuation.

The police inquiry and its potential outcome remain uncertain, with no charges filed to date. Investors are watching for further developments that could affect the company's leadership and governance.

Some analysts argue the market reaction may be overdone, noting White has denied any wrongdoing and the investigation is in its early stages.
