A 22-year-old mother was horrifically branded with hot tongs by her husband and his father because she received a call from an unknown number.

The woman, named Jhamku, suffered burns all over her body because she they suspected she was having an affair.

Her husband, Bhagga Gameti, and his father, Lehri Lal, reacted angrily and spoke to the caller, but could not identify who he was.

They first beat her with sticks before burning her legs, face, chest and genitals with hot tongs.

The helpless woman, who has a toddler son with her husband, kept crying for mercy but they did not stop torturing her, and a large crowd gathered outside their home in Udaipur, Rajasthan in northern India.

Her ordeal lasted for two hours before she was left to writhe in pain.

It was only after news spread to nearby villages that Sunday's incident was reported to local police, but Bhagga was not arrested until Wednesday.
