Jamuna Mahto poured kerosene on his body from a lantern and lit a matchstick in a bid to immolate himself last night and sustained 75 per cent burns, jail superintendent Virendra Kumar said today.
Jail doctors referred him to Patna Medical College and Hospital, Kumar said.
The prisoner, a native of Sijhauri village of Sheikhpura district, had been lodged in the jail for three months in connection with the murder of his daughter in-law for dowry. His son too is in the same jail in the case, while his wife and daughter were released on bail recently.
An investigation was on into the incident, Kumar added.
