Union Minister Smriti Irani on Friday claimed that the Left design in the Jawaharlal Nehru University has been unmasked by Delhi Police as it blamed four Left-backed student organiations for recent violence at the university campus.

"Left design in JNU unmasked. They led mobs of mayhem, destroyed public property paid for by taxpayers, disallowed new students from being enrolled, used the campus as a political battleground. #LeftBehindJNUViolence becomes public knowledge as @DelhiPolice releases evidence," Smriti Irani said in a tweet.

Delhi Police told media that it has identified nine people, including JNUSU president Aishe Ghosh, as suspects in the JNU violence case. Most of the other people identified so far by the police are members of Left-wing students organisations.

The police have said that the violence was part of Left-backed student organisation's efforts to block the registration process of students. The police named Students Front of India, All India Students Federation, All India Students Association and Democratic Students Federation for their alleged part in violence during the press conference.
