Senior Supreme Court lawyer and Team Anna member Prashant Bhushan was beaten up inside his chamber here by young men for his alleged comments on Kashmir.
Three activists belonging to the Bhagat Singh Kranti Sena entered Bhushan's chamber and assaulted him.
The police have arrested one of the attackers. According to reports, an FIR has also been registered in this regard.
Bhushan has been taken to the Ram Manohar Lohia Hospital. He was reported to be out of danger.
The Kranti Sena youth reportedly attacked Bhushan for his statements on Kashmir, which supported the demand for 'Azadi' and shifting of Army from Jammu and Kashmir.

The lawyer was pulled out of the chair, slapped, dragged and repeatedly punched. He was pinned down on the floor and kicked on his chest.
Bhushan's shirt was torn and his spectacles fell when he was roughed up. As his staff and others gathered, one of the two attackers managed to escape while another was caught by them and handed over to police.
Bhushan was later taken to the Ram Manohar Lohia hospital.
The youths had entered his office claiming that they had an appointment with Bhushan, a prominent Team Anna member who is in the forefront of the fight for a strong Lokpal.
After the attack, Bhushan said it appeared that the youths targeted him for his stand on Jammu and Kashmir.
"They were saying that I have made some comments on Kashmir to which they were taking objection. I have said that a referendum should be held in Kashmir," he said.
A case has been registered and one person has been arrested. Reacting to the attack, activist Kiran Bedi said it was absolutely shocking and shameful.
"I am very distressed. But you got evidence, I think these people will be in jail for a long time now. "It shows the amount of intolerance level we have reached. I don't know what they are him up for, but they don't know they are beating up such a good man who continues to work for the community day in and day out," Bedi said.
