The incident occurred on the intervening night of June 2-3, when Ramakant Kushwaha (19) and Sube Kushwaha (20) asked the 11-year-old girl to come to their place under the pretext of charging her mobile phone, they said.
The duo then took her to a nearby agriculture field and raped her, police said, adding that they also switched off her mobile phone so that she remained untraceable.
The girl's father could contact her only after she switched on her mobile phone after she escaped from the clutches of the accused, police said.
It is not known how the accused are connected to the victim's brother-in-law.
The victim will be taken for medical examination tomorrow, they said, adding that a case of gang rape has been registered against the accused who are untraceable.
