The SAI Action Council has demanded a criminal inquiry by the Central Bureau of Investigation (CBI) into the recent death of Aparna, a resident of the Sports Authority of India (SAI) hostel here. The council staged a dharna in front of the SAI centre on Wednesday. Council convenor Anil Bose said the ongoing inquiry was inadequate. Addressing a meeting at the venue, he said there were attempts to sabotage the investigation at the highest level. He expressed surprise ‘at the way in which the contents of the interim report were disclosed to the media.’ The agitation seeking justice to the students would continue, he said. The council would take out a march to the collectorate on June 11.
