MUMBAI, Sept. 25 -- The parents of an IIT Bombay student, who allegedly died by suicide last week, began an indefinite hunger strike at Azad Maidan on Thursday evening after meeting the chairperson of the National Commission for Scheduled Castes (NCSC). The students' parents had initially planned to stage their protest at IIT-B's main gate. However, on Thursday morning, police stopped them five kilometre away from the campus. They were later taken to the government's Sahyadri Guest House where NCSC chairperson Kishor Makwana met them. Advocates Nikhil Kamble and Siddharth Ingale, who are providing legal aid to the parents, said Makwana asked the parents whether they had faith in the ongoing investigation. The parents then raised concerns about the CCTV footage related to the student's death, which has been widely circulated. They questioned how the footage, which they described as important evidence, became available publicly, and told Makwana they wanted an inquiry into this. The parents submitted their representation of 12 demands to the NCSC chairman during the meeting and reiterated their demand for action against those named in the case. They also demanded that the investigation be handed over to the CBI. They said they would remain on strike until Prof Suryanarayana Doolla was arrested and their other demands were addressed. Late on Thursday night, however, police denied them permission for Friday over Ganesh visarjan. They will continue on Saturday....
