The petition by Pranab Kumar Gupta also appealed that the investigation into the death of Sudipto be monitored by the court, his counsels Bikash Bhattacharya and Rabishankar Chattopadhyay said.
Stating that only the driver of the bus, from which Sudipto had allegedly fallen while being taken to Presidency jail, had been arrested, the father claimed that the investigation had not proceeded further.
The police had maintained that Sudipto, a MA student of Rabindra Bharati University, was hanging from the foot-board of the bus when his head hit a lamp post while being taken to jail after a law violation programme by SFI on April 2.
