Chandra Shekhar was in Lucknow to join the anti-CAA protests at the Clock Tower in the state capital.

Additional DCP Chiranjeev Nath Sinha, however, denied that the Bhim Army chief had been taken into custody.

"Additional forces were sent to the guest house when we learnt of his presence there. He has probably come here in connection with meetings of his organization," the police official said.

Bhim Army's media in charge Anurag maintained that Chandra Shekhar was under house arrest and was not being allowed to join the anti-CAA protests.

Chandra Shekhar has been touring the country in support of anti-CAA protests and has even been arrested once in this connection.
