Rakesh Sonawane, Bidve's brother-in-law, said the family has still not been told when his body can be returned to India for Hindu funeral rites and has not been given details about the medical treatment he received after the shooting.
"We still have a lot of faith in the U.K. authorities and the police, but they have to help us more," Sonawane said. "They have to help us to believe again that Britain is not a racist place."
Bidve, a graduate student in micro-electronics at Lancaster University, was from Pune, a city 80 miles southeast of Mumbai. He and some Indian friends from the university had come to Manchester for the holiday and were walking into the city center when Bidve was approached by two men.
Investigators are treating the shooting as a hate crime and have offered a $78,000 reward for information. Five people ranging in age from 16 to 20 were arrested, although the three youngest have been freed on bail.
