According to The Times of India, the incident occurred in Lakhimpur Kheri, Uttar Pradesh, India.
Officials said the woman and daughter had been residing with the man for two years after the 36-year-old mother divorced her alcoholic husband.
The woman who talked to the Times of India said she was working at a farm at the time of the alleged occurrence.
She said she arrived home just in time to catch her partner “red-handed” attempting to rape her adolescent daughter.
She also said that he attempted to attack her as she tried to stop him.
She said, “I was trying to save my daughter and hence got hold of a kitchen knife and chopped off his p*nis to teach him a lesson. I have no regrets.”
The woman’s boyfriend has reportedly been arrested for rape under the POCSO act, according to the SHO of the Lakhimpur police station.
The SHO added that the accused’s condition is critical and that he might be transported to Lucknow for better medical care.
It is unknown if the mother, who has not been named, will be charged with anything for chopping the boyfriend’s manhood.
