Kolkata, 8 July: Kolkata Police suffered a major setback in the case of the death of young SFI activist Sudipto Gupta after the West Bengal Human Rights Commission (WBHRC) found that the driver, who drove the vehicle carrying the protestors, didn’t possess a driving license.  WBHRC, which ordered a probe, found that Mr Raja Das was driving the vehicle without any driving license.Mr. Rabindranath Samanta, registrar of WBHRC, confirmed that the full bench of the commission today concluded: “On 2nd April, the driver was driving the vehicle without driving license.”This conclusion further strengthens the speculation that Kolkata Police itself violates law.     sns
