"No comments," was the quick response from Dal Khalsa leader Kanwarpal Singh.
Pressed further, he told IANS: "The London police have not yet identified anyone for the attack. It is not known who has done it. The details are sketchy."
The Shiromani Gurdwara Parbandhak Committee, the mini parliament of Sikh religion, has cautiously refrained from saying anything.
It has also issued a diktat to SGPC members, saying their comments were not the official line of the SGPC.
Following the London attack Sunday evening off Oxford Street, Brar, 78, who gets 'Z' category security in India as he is on the hit-list of Khalistani militants, openly blamed the Punjab government, led by the Akali Dal, for encouraging fringe Khalistani elements by allowing a memorial to be built in June this year for "martyrs" of the 1984 Operation Bluestar. Brar has been opposed to the memorial.
Operation Bluestar was conducted by the army to flush out heavily armed militants from inside the Golden Temple complex in Amritsar, 250 km from here. The complex, except for the sanctum sanctorum, suffered heavy damage.
"The motive was not robbery. The motive was assassination. They wanted me dead," Brar told CNN-IBN news channel.
"Had I not fought back, I would not be here speaking to you," said Brar, who had a bandage around his neck and is now back in Mumbai. His wife was also injured in the attack.
