The woman says that her husband has been beating her up since many years.

Fed up with years of physical and mental torture, a woman in Assam's Lakhimpur district killed her husband and landed at the local police station with his severed head.

The incident took place late Tuesday night when the woman from Mazgaon arrived at the Dhalpur police outpost carrying her husband's head in a plastic bag.

The accused, Guneswari Barkataky, 48, confessed of killing her husband Mudhiram, 55.

"He had been beating me for many years. On several occasions, he even injured me with an axe. I had thought of leaving him long ago, but did not do so because of our children. When it became unbearable and I had to do it, else he would have killed me," the woman said.

The mother of five - two sons and three daughters - allegedly attacked her husband with a machete and walked nearly five kilometres to the nearest police station carrying his severed head in a plastic bag.

"The woman came to the police station with her husband's head and surrendered. On being questioned, she admitted to killing her drunk husband in a fit of rage to escape his abuse. We are conducting further investigations," said a local police official.

A local court on Wednesday sent the woman to judicial custody.
