A Hyatt Regency Waikiki employee says hotel officials continued to accommodate a guest who groped her because the guest is a member of an entourage, headed by a Middle Eastern prince, that regularly spends millions of dollars at the hotel.

The employee, Michelle Silberstein, filed a lawsuit in state Circuit Court on Tuesday against the hotel and the guest, California resident Hassan Maan Melhem.

Melhem, 60, pleaded no contest to two counts of misdemeanor sexual assault in March. A state judge granted him a deferral of his no-contest pleas, giving Melhem the opportunity to have the charges dismissed if he stays out of trouble for a year. The judge also fined Melhem $1,000.

Silberstein says in her lawsuit that the prince has been a special guest of Hyatt for several years, paying for an entourage of 12 to more than 20 Middle Eastern businessmen, including Melhem. She says the prince books entire floors of the hotel for weeks or months at a time.

Melhem’s lawyer, Michael Green, says the entourage usually occupies two or three floors, once or twice per year. He says Melhem is fighting the lawsuit.

Silberstein says she has been a licensed massage therapist and esthetician for Hyatt since 2004. She says hotel officials cater to the prince’s every request and provide his entourage exclusive access to the hotel’s spa for extended blocks of time after hours. She says hotel officials also let members of the entourage select who will service them based on looks by requiring spa employees to line up for the guests.

On Aug. 13, 2014, Silberstein says Melhem showed up for a facial that another member of the entourage had requested and instead ordered her to give him a body scrub. As she was doing her job, Silberstein says Melhem harassed and groped her, then after she broke free offered her a gift if she went up to his hotel room.

Silberstein says she reported the incident to the spa director, who told her the report would be forwarded to hotel security the following morning. When she went back to work the next day, Silberstein says the hotel’s head of security discouraged her from filing a police report. She filed a report and police arrested Melhem.

Following Melhem’s release, Silberstein says she learned that not only did hotel officials allow Melhem to continue staying at the hotel, they allowed him continued use of the spa. Silberstein says she has not gone back to work since.

A Hyatt spokeswoman said in a written statement, “The safety and well-being of our colleagues are top priorities for Hyatt and we treat all safety concerns raised by our colleagues seriously.”
