Nadeem was arrested on Wednesday for allegedly raping and physically assaulting the girl for two years.
Police said the girl, who is from Bihar, got raped for the first time by her employers' son Nadeem two years back.
Nadeem's parents apparently did not stay with them and he had been beating and sexually assaulting her in their absence.
A medical examination of the girl, who was working for the accused for the last three to four years, has confirmed rape and physical abuse.
"On Tuesday night the girl was brutally beaten up by the accused after which she approached a neighbour, who informed police about the incident. Nadeem was arrested while the girl has been handed over to the Child Welfare Committee (CWC)," said the official.
According to the official, Nadeem has been charged with rape, causing grievous injuries, and voluntarily causing hurt. He is currently in judicial custody.
The official informed that the teenager was also allegedly tortured by her employers' daughter Fardeen.
During the medical examination, burn marks were found on the girl's right hand, which were allegedly made by Fardeen.
The police are yet to arrest Fardeen and her mother Juhi.
