An Indian woman who was allegedlyraped and set on fire killed her attacker by dragging him into the flames, police said Wednesday (Mar 6).

The woman survived with burns to her face and hands while the man died in hospital from his injuries.

The widow, 35, told police that the man, 42, attacked and raped her in her home north of Kolkata in eastern India on Monday, when her daughters were out.

"Then he poured kerosene on her body and set her on fire," police officer Sajal Kanti Biswas said, quoting the woman's statement.

Locals had rushed to the woman's house after noticing smoke, Times of India reported. They later found both of them on fire and a jar of kerosene in a room. 

Both of them were then taken to a local hospital, the report added, before they were brought to Malda Medical College and Hospital, where the woman is being treated.

The man died from his injuries on Tuesday morning, the report said, citing police. 

The woman has three daughters, according to the Times of India. 

India has a grim record of sexual violence, as highlighted by the gang rape and murder of a woman on a Delhi bus in 2012.

On average, more than 100 rapes were reported each day in 2016, according to the most recent official figures.

Victims are often threatened by the perpetrators against reporting the incidents to the authorities.

A slow judiciary and lax policing system also fail the victims, experts say.

In recent years some incidents of victims taking drastic actions for "instant justice" have surfaced.

Last December, a 47-year-old woman cut off the penis of her stalker after the 27-year-old repeatedly sought sexual favours from the mother of two.
