The case only came to light after the woman managed to escape the couples' Katy home in the Arroyo Hill Court in Houston, and called the National Human Trafficking Hotline for help.
Special agents with the Homeland Security Investigations Houston Human Trafficking Group have begun interviewing the couple, family members, and the victim.
Chudy, 56, and Nsobundu, 50, are charged with forced labor, withholding documents, conspiracy to harbor an illegal alien and visa fraud. Court documents also reveal both husband and wife were naturalized United States citizens originally from Nigeria.
Court documents reveal that the woman 'arrived to the United States from Lagos, Nigeria, in September of 2013, and was granted a visa for two years.'
The couple had promised to deposit $100 a month into her Nigerian bank account for the care of their children, and after five years, they would pay for her to return to Nigeria but according to prosecutors, the woman recently realized the couple never deposited any funds into her account, after they had seized her passport.
The allegations in a court filing said the nanny claims she was forced to work 'every day from 5:30 am. until 1 am, cleaning the house, cooking and taking care of several children. The nanny was also not permitted to eat fresh food but only left over food.'
The husband and wife who appeared in federal court on Tuesday, have been released on bond pending their sentencing.
