Masked protesters take out torchlight march against JNU case

Masked goons attacked Jawaharlal Nehru University's students in which more than 18 were injured. Among them were few professors as well. But the question here is, who all are actually behind the attack? Howcome the masked goons knew all about the university? With these questions, masked Indian Youth Congress members held a march from Raisina Road to India Gate against violence at JN. The protest took place near India Gate in Delhi.
