The girl has been badly injured and was rescued by a joint team of an NGO and police. The NGO had received information in this regard and informed the police.
Medical examination on the girl was conducted, said a police officer.
"There are knife injuries on her head and hand. There is a deep gash on her head as well," said police.
The girl reportedly told police that she had been working with her employers for the past one year and they used to beat her up almost every day, apparently not happy with her work.
