Less than 16, the domestic help is reportedly pregnant.
A teen domestic help was allegedly sexually assaulted repeatedly by a lawyer and his son at their apartment in Hyderabad, the police said on Wednesday.
The family, which stays in Greenhills Colony in the city's Chaitanyapuri area, brought the girl six months ago from Suryapet, around 140 km away. Less than 16, she is reportedly pregnant.
Sudhakar Reddy, 60, and his 30-year-old son Bharat Kumar Reddy, both lawyers, have been arrested.
Cases of crime against children, rape and sexual assault and bonded labour have been filed against them.
The lawyer's older son, Tarak Ram Reddy, has also been charged with assaulting a neighbor on suspicion that he reported the family to activists.
Sudhakar Reddy's wife and daughter also live with him.
When the help complained about assault some months ago, she was allegedly beaten. She had no access to any phone.
