Students from various varsities across Delhi, who have been agitating against the alleged delay in justice to Rohith Vemula, today said that a video showing Delhi Police personnel thrashing demonstrators was a "proof" of how protesters are treated. "Students have been raising their voice in recent years also but never has their right to protest been snatched like this. Every time we try to take out a peaceful demonstration, we are beaten up, ill treated and attacked. This video is a proof," said JNU Students Union Vice President Shehla Rashid Shora. Another protesting student Sucheta De, alleged, "protesting against whatever we find inappropriate is a constitutional right guaranteed to every citizen. We have to face similar assaults every time we try to raise our voices. It is for those in power to see what this video reflects of our police force". "Many times when we have been detained while protesting, we have been told by policemen that we should refrain from creating ruckus as they have been told not to let us do so. Who is instructing them to attack on students?," said Sunny Kumar, student and member of left-backed All India Students Association (AISA). The students' reaction comes in the wake of a video which went viral on social media, showing male police constables purportedly assaulting protesters, including women, demonstrating over the suicide of Dalit scholar Vemula near the RSS head office here. The students from Jawaharlal Nehru University had decided to go on an iNdefinite hunger strike last week when they were detained from outside HRD Ministry for staging a protest there. "The strike is still on..we will continue to fight for justice for Rohith. It is not just about him but about every student's rights," Shohra said. The students have been demanding the resignations of Union ministers Smriti Irani and Bandaru Dattatreya and the Vice-Chancellor of Hyderabad University over the death of Vemula.
