Amir Malik alias Vicky (34), who sustained over 80 per cent burns, succumbed to his injuries last night at Jalandhar hospital, police said.
Mr Malik, who belonged to a nearby Samrai village, was deported from Australia one-and-a-half-months ago and had an affair with a girl, police said.
In his statement given to magistrate, he had claimed that he was kidnapped and bundled into a car by the four members of the girls' family, blindfolded, beaten badly at an undisclosed place and then set ablaze, said Satnampura SHO Bharat Masih.
The SHO said that a case under IPC Section 302 (punishment for murder) was registered against Sandeep, Saket, Jassi and Gurminder Singh.
However, girl's uncle Rajesh Kumar alleged that since they were opposed to their relationship, Mr Malik wielding a sharp-edged weapon and a bottle of petrol in his hands, yesterday came on his bike and allegedly barged into their house and threatened to immolate himself in case the girl was not allowed to go with him, police said.
Mr Kumar said that they tried to douse the fire but the youth had sustained serious burn injuries by that time.
Mr Malik was rushed to local civil hospital from where he was referred to Jalandhar as his condition was critical, police said.
Police said that on a complaint of Mr Kumar, a case was registered against Malik under sections 452 (house trespass after preparation for hurt, assault or restraint), 324 (voluntarily causing hurt by dangerous weapons or means) and 506 (punishment for criminal intimidation) of IPC.
Earlier also, he was booked under these and other relevant Sections of IPC for attacking Sanket David, girl's brother-in-law, at Chaheru village on August 3, police said.
