Australian Federal Police, responding to a request from U.S. authorities, arrested the prominent stock market trader Saturday after he flew into Sydney to begin a month-long speaking tour in Australia and New Zealand.
The U.S. Internal Revenue Service has been seeking the 64-year-old Virgin Islands resident over allegations that he evaded $1.5 million in taxes on royalties from his books on the stock market and proceeds from international seminars between 1990 and 2001.
His daughter, 25-year-old Michelle Williams, was nominated for a best supporting actress Oscar for her role in 2005's "Brokeback Mountain."
Williams was freed on $753,000 bail, ordered to surrender his passport and report to police three times per day.
He is due back in Central Local Court on Monday.
