The Ferozepur police arrested the main accused in a case where a family had been set on fire, from Ambala in Haryana on Saturday morning.
Giving details, SSP Varinder Pal Singh said here that Lakhwinder Singh was the mastermind behind a revenge attack in which six members of a farmer's family were set on fire at their house at Jattawali village in this district in the wee hours of Thursday.
Three of them -- an elderly woman and her two minor granddaughters - died, while the others were injured.
Various police parties were sent to nab Lakhwinder in Kota in Rajasthan and Mathura in Uttar Pradesh as they had a tip-off. On Friday night, he was at Mathura but later he boarded a train to Ambala, where another police team led by Jagdev Singh, SHO Mallanwala police station, arrested him near the Ambala railway station, said the SSP.
During the preliminary interrogation, Lakhwinder confessed to his crime, saying in the past one month he had twice tried to commit the crime but had failed, said the SSP.
He said that while committing the crime, the accused threw petrol on the victims from a bucket and while doing so his fingers also got burnt.
Farmer Balwant Singh was sleeping in the courtyard of his house with his wife, three children and mother when five people climbed up the roof from the rear side around 3.30am on Thursday.
They poured petrol on the family and threw a burning 'mashaal' (wooden torch) on them before fleeing from the spot.
Balwant's mother Bachan Kaur (70) and daughter Jasvir Kaur (17) died on the spot, while another daughter, Satvir Kaur (16), succumbed to injuries at a local private hospital. Balwant suffered 70% burns and was referred to Dayanand Medical College and Hospital, Ludhiana, where his condition is stated to be stable.
His wife, Veerpal Kaur, with 15% burns on the arms and face, and son Sukhpreet (10% burns) were admitted to a local hospital.

So far Lakhwinder and Mohan have been arrested while a manhunt is on to nab the other accused.
