Delhi Police on Saturday registered a case in connection with posters announcing a "reward" of Rs.11 lakh for anyone who "shoots down" JNUSU president Kanhaiya Kumar.

One person was caught while he was sticking the posters on the behalf of outfit ‘Purvanchal Sena’ on the wall of Press Club while others accompanying him managed to flee. The matter was reported to the police.

"A case has been registered under relevant sections of law at the Parliament Street police station," said a senior police officer.

"The person fixing the posters was questioned at the police station and we are tracking others who got the posters published," he said.

"No person has been arrested so far in this connection," said Taj Hasan, Special Commissioner (Crime) and chief spokesperson of Delhi Police, without divulging any further information.

The development came on a day BJP Yuva Morcha leader Kuldeep Varshnay, who had announced a reward of Rs 5 lakh for cutting off JNU Students union leader Kanhaiya Kumar’s tongue, was expelled from primary membership of the party for six years.

The poster stated that "whosoever shoots JNU students union president and seditionist Kanhaiya will be rewarded Rs 11 lakh on the behalf of Purvanchal Sena." 

The poster carried name of one Adarsh Sharma as president of Purvanchal Sena. A mobile phone number was also mentioned on the posters but it was not reachable despite several attempts.

Kanhaiya was arrested on February 12 in connection with a sedition case over a controversial JNU event. He was granted interim bail for six months by the Delhi High Court on March 2 and was released from Tihar jail next day.
