The body of 25-year-old Ranjodh Singh, who was killed in Australia last month, was flown back to New Delhi on Friday.
The body arrived at the Indira Gandhi International Airport and was handed over to his brother Satnam Singh and other grieving relatives.
A bitterly crying relative said the Australian authorities have said that they have arrested some people but the family doesn't know what action is being taken.
Ranjodh Singh was set alight and left to die in the New South Wales farming town of Griffith. His charred body was found in December last year. Three Indians - including Gurpreet Singh, 23, and his wife Harpreet Bhullar, 20 - were arrested for Ranjodh Singh's brutal killing.
