OnlinePoker.net reports that a 51 year old passenger aboard the SuperStar Aquarius lost HK$5 million ($650,000) playing baccarat.  He then leaped to his death from the top floor of the 13-deck cruise ship.

The article identifies the passenger as “Xu” and states that he gambled at the baccarat table until it closed at 8 a.m. on Sunday.  After losing this staggering amount, “Xu then wandered the deck for an hour before he was seen jumping to his death .  .  .”

A police spokesman classified the incident as “man overboard,” with no suspicious circumstances.

The cruise ship is operated by Star Cruises.
