Activists of a fringe right-wing group had on Tuesday attacked the AAP office at Kaushambi in Ghaziabad to protest the controversial remarks of its senior leader Prashant Bhushan on the presence of security forces in Jammu and Kashmir.
"BJP as usual has dissociated itself from the attack and it was part of their strategy," he alleged.
Claiming that over 150 organisations have their roots in the Sangh, Singh tweeted, "If one hand strikes, the other applies balm."
"Doesn't it remind of the character in the Ramayana who had 10 faces and one body?" he asked.
Armed with sticks and bricks, a group of 40 Hindu Raksha Dal activists had stormed the AAP office near the residence of Delhi Chief Minister Arvind Kejriwal.
Bhushan, who is under fire for his remarks on Kashmir, blamed the BJP and RSS-affiliated organisations for the attack on the party office, saying they were "extremely frustrated with the rise of AAP".
"I strongly condemn the attack on AAP office," Singh wrote on micro-blogging website Twitter on Tuesday night.
