Kanhaiya Kumar is one of the accused for holding an "anti-national" event in JNU in 2016.

A court in Delhi today pulled up the Delhi police for filing a chargesheet against former Jawarharlal Nehru University (JNU) students' union leader Kanhaiya Kumar without getting approval from the Delhi government.

"You don't have the approval from the legal department, why did you file the chargesheet without approval?" the court told the police while hearing the matter.

Metropolitan Magistrate Deepak Sherawat has asked the police to get requisite approval by February 6. The court was told they will get the approvals within 10 days.

The Delhi police on Monday filed a 1,200-page chargesheet against Kanhaiya Kumar for allegedly holding an "anti-national" event at the JNU in Delhi in February 2016.

Umar Khalid, Anirban Bhattacharya and seven students from Jammu and Kashmir -- Aquib Hussain, Mujeeb Hussain, Muneeb Hussain, Umar Gul, Rayeea Rassol, Bashir Bhat and Basharat -- have been named in the chargesheet.

They have been accused of organising an event on the campus against the hanging of Parliament-attack mastermind Afzal Guru. Their arrests had triggered a huge controversy with the opposition slamming the police for "working at the behest of the ruling BJP".

Both Kanhaiya Kumar and Umar Khalid have said the case against them was "politically motivated".

"When the magisterial inquiry was done, it was concluded that no JNU student was involved. I want to say, the police filed a chargesheet after three years. We thank them," Kanhaiya Kumar told NDTV.

"The filing of chargesheet after three years, ahead of elections, clearly shows it to be politically motivated. I trust the judiciary of my country," he told news agency ANI.
