Kolkata rape case: SIT probes accused's call records

Kolkata Police's Special Investigation Team is digging deep into the alleged rape at a city law college.
Vice-Principal Nayna Chattopadhyay has already been questioned twice as investigators try to figure out her role.
They're also going through call records of the suspects—especially one from prime accused Monojit Mishra to Chattopadhyay, made just a day after the incident.
