The condition of the girl, who is now in the Trauma Centre of King George's Medical University hospital, is said to be stable.
According to the FIR lodged by the victim's father, the attack took place late on Saturday afternoon when the girl's father was away for work and her mother was on the terrace.
Sarvesh Rawat (32), a private company employee and father of three, sneaked into their house and grabbed the girl.
As he gagged her and imposed himself on her, the girl's mother came into the room and tried to rescue her daughter.
Rawat overpowered mother and daughter and thrashed them. He also allegedly raped the girl and left after threatening them with dire consequences.
The girl's father said that the police attitude towards them was pathetic and it took him hours to get his complaint converted into an FIR.
The police finally arrested accused Sarvesh Rawat on Sunday after the victim consumed poison and charged him with rape under IPC and POCSO Act.
SHO Vipin Kumar Singh said that a case of rape had been registered against Rawat.
"He was arrested after a manhunt and has also been booked under POCSO Act since the girl is a minor. She is under treatment and her medical examination will be conducted," the officer added.
