A woman is charged with beating and starving a woman she brought from China to the US to work as a nanny, holding her in a state of "slavery", a prosecutor says.
Lili Huang, 35, of Woodbury Minnesota is charged in Washington County with five felony counts, including labour trafficking, false imprisonment and assault. Huang remains in jail after making her initial court appearance on Friday, the Star Tribune reported.
The 58-year-old woman, who is not named in the complaint, arrived in the US on a visa in late March. According to the complaint, the nanny was forced to work up to 18 hours a day doing child care, cooking and cleaning. Police calculate her pay at about $US1.80 ($A2.36) an hour, but she apparently did not receive any of it.
The woman recently was found wandering in the street, her eyes blackened. A hospital exam found she had many broken bones.
She was rationed crackers for meals and her weight had dropped from 54kg when she arrived in the US to 40kg the complaint said.
The woman was never allowed to leave the house, the complaint said.
The nanny told a police investigator she eventually fled the house when Huang threatened to kill her with a knife. She told police she was looking for the airport so she could go home to China, the complaint said.
Washington County prosecutor Pete Orput said the nanny was held in appalling conditions, the St Paul Pioneer Press reported.
