Hongxia Wang, 57, filed a lawsuit claiming Dr Derek Enlander (pictured) and his wife, Caron, sexually abused her for several years

A wealthy couple has been accused of sexually abusing a Chinese immigrant, whom they promised a better life.

Hongxia Wang, 57, filed a lawsuit this week that claims fibromyalgia doctor Derek Enlander and his now-deceased wife, Caron Enlander, lured her into their Fifth Avenue home in 2000 and forced her into years of manual labor.

The lawsuit alleges that the Enlanders promised to pay her $80 an hour for spa treatments and massages, according to the New York Post.

At the time of the Enldander's offer, Wang was reportedly only making $45 a day at a nail and hair salon.

But instead of a better life, Wang was allegedly subjected to years of forced labor and sexual abuse that lasted until 2011, according to the suit filed in Manhattan federal court.

According to the Post, Wang claims she was a 'slave' who washed their dishes, cleaned their boat and made their lunches.

The woman says that she was also forced to have sex with them.

From 2000 to 2003 , Wang claimed she was Caron's lover. Caron, who died in 2006, was a diamond-dealer in New York. She became the first woman to sit on the Board of the Diamond Dealers Club.

Shortly after his wife died, Derek Enlander began forcing himself on her in 2007, the lawsuit alleges.

'Dr Enlander refutes the allegations and we are confident he will be vindicated,' his lawyer, Tom Mullaney told the Post.

Wang said she stayed with the Enlanders because they kept promising to help her obtain a green card.

She is seeking damages in an amount to be determined a trial.

Derek Enlander, who currently operates the ME/CFS Medical Center located on the uper east side of Manhattan, is from Belfast, Northern Ireland.

He came to New York as Assistant Professor of Medicine at Columbia University and then Associate Director of Nuclear Medicine at New York University.
