NEW DELHI: The Supreme Court on Thursday asked the Centre to preserve the ammunition log of RAF deployed at Jantar Mantar during students’ protest against NEET paper leak. It referred to the advisory of the Bureau of Police Research and Development (BPRD) and said police are empowered to use pellet guns in exceptional situations. The bench, however, said it was ready to examine the use of pellet guns in the July 20 protests called by Cockroach Janta Party (CJP). Taking note of the submissions of Grover, the bench asked the Centre, represented by Solicitor General Tushar Mehta, to preserve the ammunition log of RAF (Rapid Action Force) deployed at Jantar Mantar during the protest. The petition also seeks exemplary compensation, comprehensive medical treatment and rehabilitation for all persons allegedly injured in the incident.
