Police on duty there prevented her from doing so and took her to the police station, police said.
The woman alleged that her acquaintance Ganesan, an autorickshaw driver and his wife Kalavathi requested her to give the document of her house site for buying a car. Besides, they took her signature in several papers.
A few days later she was shocked to learn that the land had been grabbed by the couple.
Frustrated over this, she tried to immolate herself even as the officials were hearing the grievances of the public.
