A guest who took up residence for nearly two months in a room at the Tribeca Grand hotel, allegedly using it as home base for her phony investment company and racking up $33,000 in hotel expenses along the way, now has a room at a less desirable address-Rikers Island.

Police arrested 52-year-old Elonoa Sikivou on June 9 at the hotel when management there learned the credit card she had supplied them was canceled due to unauthorized transactions.

According to court documents, Sikivou had been using the credit card of one of the many "clients" caught up in her investment scam.

The Fijian woman, who once ran for parliament in the island republic, claimed to head an international investment firm and allegedly conned clients out of tens of thousands of dollars. Prosecutors are seeking a grand jury indictment on at least two counts of grand larceny in connection with the scam and may bring more charges as additional victims come forward.

"The investigation is continuing," a spokeswoman for the District Attorney's office said.

Sikivou allegedly bilked one Manhattan man out of $60,000 he had paid her since Nov. 17, 2003, in return for investments and other services, according to court documents.

The man also claimed that Sikivou had signed over a counterfeit check from Rolex Watch Company in the amount of $61,000 in April.

A grand jury indicted Sikivou in June on one count of criminal possession of a forged instrument in the second degree in connection with passing the check. A grand jury was set to convene in July to consider second- and third-degree grand larceny charges against her in connection with the investment scam and her bill at the Tribeca Grand. If convicted, she faces up to 15 years in prison.

Sikivou gave police a Pasadena, Calif., address at the time of her arrest. She had been a guest at the Tribeca Grand hotel from April 15 through June 9.

An editor with the Fiji Times, the island chain's largest daily, said Sikivou had been a social worker there and ran unsuccessfully for parliament in 1999. "I do remember that she contested the results when she lost," he said.

In court last month, Sikivou stood silently in heels and a pantsuit as she was arraigned on the criminal possession charge. Then she was ushered back to her cell at Rikers, where she will remain until she can post $250,000 bond.
