The wife, Amrita Rai, suspected the husband, Ashish Kumar Rai, of having an extra-marital affair.
"I was visiting my in-laws. They confiscated my mobile and the keys of my motorbike. When I asked for the keys, they said you should stay today. I said okay to that. Then we all slept," said Ashish Rai, a native of Balia.
"At 3 in the night, my wife said she is going to visit the washroom. Her sister had kept the boiling water ready. She threw the water on me while I was asleep. When I tried running, they got hold of me and started thrashing me. They broke my head too. They threw me off the terrace," Mr Rai added.
An FIR has been filed against the woman and investigation is underway.
