UP to eight high-profile arrests are expected as the US Government continues its assault on online gambling websites linked to fallen Gold Coast tycoon Daniel Tzvetkoff.

The owners of the three largest sites Full Tilt Poker, Absolute Poker and PokerStars were charged with bank fraud, money laundering and other gambling offences. Authorities are seeking penalties upward of $US3 billion.

As The Courier-Mail print edition reported on Saturday, 28-year-old Tzvetkoff is believed to have cut a deal with US authorities after he was arrested a year ago for allegedly laundering up to $534 million in illegal online gambling earnings.

He faced 75 years in prison but was bailed last August and it is believed the FBI is mining his inside knowledge of online gambling transactions.

The FBI is negotiating with foreign governments to serve arrest warrants. Restraining orders have been served on 76 bank accounts in 14 countries.
