An Indian man is in a serious condition in a Melbourne hospital after being attacked and set alight by a gang.

The attack comes a week after an Indian graduate student, Nitin Garg, was stabbed to death in the city. This prompted a travel advisory from the Indian government about the safety of Melbourne. The 29-year-old was returning home with his wife when he set upon by a gang, who poured fluid over him and then set him alight.

He has burns on 15% of his body.
