Congress President Rahul Gandhi on Wednesday attacked the Narendra Modi-led government at the Centre using a “pop quiz” on Twitter that asked people to name the “perpetrator of hatred and fear”. Gandhi’s remarks came a day after alleged Bharatiya Janata Yuva Morcha and Akhil Bharatiya Vidyarthi Parishad workers attacked social activist Agnivesh in Pakur district of Jharkhand.

“I bow to the most powerful in the line,” Gandhi said in a sarcastic tweet, sharing a video of the attack on Agnivesh. “A person’s strength and power are all that are important to me. I use hatred and fear to maintain the hierarchy of power. I seek out the weakest and crush them. I rank all living beings based on their usefulness to me. Who am I?”

The Jharkhand Police have detained 20 people in connection with the attack on Agnivesh. “As soon as I came out of the venue, BJYM and ABVP activists attacked me without any provocation,” Agnivesh told PTI. “They alleged that I was speaking against Hindus.”

Jharkhand Chief Minister Raghubar Das has ordered an investigation into the matter. Meanwhile, the Bharatiya Janata Party distanced itself from the incident. The spokesperson of the party’s Jharkhand unit, P Shahdeo, said, “They weren’t workers of our party. We condemn this but his track record is such that this reaction doesn’t come as a surprise.”
