Parties condemn attack on Ramdev

Seated along with Janata Party leader Subramanian Swamy at the Constitution Club in the heart of the capital, Ramdev's right eye was blackened with ink by the man identified as Kamran Siddiqui, a resident of Delhi who is said to be running an NGO 'Real Cause' and is also a petitioner in the Batla House encounter case.

The protester before being handed over to police was roughed up by Yoga guru’s supporter. The man, whose shirt was torn and removed, was seen bleeding from his lips. There was lot of jostling around when police escorted the yoga guru away from the club.

Jaideep, Ramdev's close aide, claimed that Siddiqui had gained entry into the hall carrying a walkie talkie apparently posing as a security personnel. He also claimed that a bottle of acid was recovered from Siddiqui.

Ramdev later said he was not deterred by such attacks and would continue his campaign with full force against corruption.

"We talked about blackmoney, we talked about eradicating corruption and in return as a prize this is what I have got. However, by throwing ink on someone, one cannot malign his character," he said.

"One whose life has been devoted to fighting corruption cannot be deterred by black flags and ink," he said. Before the incident, Siddiqui had sought Ramdev's opinion on the 2008 Batla House encounter in which suspects of the Delhi serial blasts were killed.

The yoga guru had ignored the question and soon after the attack took place.

"A case under sections 153 (promoting enmity among communities) and 355 (criminal assault) of Indian Penal Code has been registered against him," a senior police official said. If convicted, he may be imprisonment for upto two years.
