Kolkata: The father of Students' Federation of India (SFI) leader Sudipto Gupta, who died in Kolkata Police action, on Friday said he will move the Supreme Court to seek justice.
"I will approach the Supreme Court to seek justice for my son," said Pranab Gupta.
Reacting to West Bengal Chief Minister Mamata Banerjee saying the SFI activist's death was an accident, Pranab said: "Mamata is making bizarre remarks to cover up the case."
Banerjee on Thursday said the death of the 22-year-old was an accident and not a result of 'police atrocity'.
The SFI is the student wing of the state's opposition Communist Party of India-Marxist (CPI-M).
"This (Sudipto Gupta's death) is an accident. It is not due to police atrocity," Banerjee told reporters here on Thursday.
Meanwhile, the Kolkata Police said the young leader had suffered head injuries after hitting a stationary blunt object.
Addressing a press conference here, Joint Commissioner of Police Jawed Shamim said: "The death was due to head injury and ante mortem in nature."
"The injuries are consistent with hitting a stationary blunt object," he said.
The West Bengal Human Rights Commission (WBHRC) on Thursday announced it will hold an inquiry into the death of the SFI leader.
Besides conducting an independent and parallel investigation, the WBHRC has asked the Kolkata Police to probe into the case and submit a report on it withing a week.
"We don't have any faith in the police as we all know that the SFI leader died in police custody. Which is why, we have decided to carry out our own investigation. A three-member team will conduct the inquiry," said a WBHRC official on condition of anonymity.
