New Delhi: The Central Forensic Science Laboratory (CFSL) has authenticated four videos related to the February 09 incident at the Jawaharlal Nehru University, saying anti-national slogans were raised during the event organised to commemorate the hanging of Parliament attack convict Afzal Guru.

The CFSL based in Gujarat's Gandhinagar has confirmed in its lab test that anti-India slogans were raised at the prestigious institute during the event.

On February 09, 2016 JNU witnessed clashes between two student groups over Afzal Guru, who was hanged on February 09, 2013 in Tihar Jail.

The incident happened after a group of students organised a programme and termed the hanging of the Parliament attack convict as "judicial killing”.

The students allegedly shouted slogans hailing 'Shaeed Afzal Guru' and also chanted anti-India slogans. They also expressed solidarity with "struggle" of Kashmiri migrants and advocated for 'Azad Kashmir'.

Some of the slogans raised from JNU campus were:-

Tum kitne Afzal maroge, ghar-ghar se Afzal niklenge

Pakistan zindabad

Kashmir maange azaadi, ladkar lenge azaadi

Kashmir ki azaadi tak, jung rahegi-jung rahegi

Bharat ki barbaadi tak, jung rahegi-jung rahegi

Afzak ki hatya nahi sahenge

Delhi Police had arrested JNU students Kanhaiya Kumar, Umar Khalid, Anirban Bhattacharya under sedition charges. Later all three were released on interim bail by the High Court.

Taking tough action, the JNU administration rusticated Khalid and Bhattacharya. Umar was also slapped with a fine of Rs 20,000, while Anirban has been barred from the campus for five years from July 23.

JNUSU president Kumar was fined Rs 10,000.
