Bengaluru Noted historian Ramachandra Guha and many others were detained on Thursday for staging a demonstration against the Citizenship Amendment Act and NRC at the Town Hall here, in defiance of the prohibitory orders imposed in the city.
Police said the protesters violated prohibitory orders clamped in the city against any protest or demonstration.
Reacting to his detention, Guha said it was "absolutely undemocratic" that police were not allowing even a peaceful protest, which is the democratic right of the citizens.
The Communist Party of India too staged demonstrations in the city against the CAA and NRC.
Condemning Guha's detention, Makkal Needhi Maiam chief Kamal Haasan on Thursday lashed out at the police actions during the anti-CAA protests, and expressed "concern" over his safety.
He also condemned the detention of Swaraj Abhiyaan chief Yogendra Yadav and Guha who was detained during the protests in Delhi.
In a tweet, Haasan said he was applauding with "glee the stupidity of the government for stoking the fire of Satyagaraha by arresting" Guha and Yadav.
"I applaud with glee at the stupidity of the government for stoking the fire of Satyagraha by arresting the thinking and questioning minds of India like @Ram_Guha & @_YogendraYadav," he said in the tweet. "Yet I am concerned for their safety. India stands with you," he added.
Yadav was among those protesters who were detained by the Delhi Police near Red Fort when they tried to take out a march in defiance of the prohibitory orders imposed to protest the Citizenship (Amendment) Act.
Guha, a noted historian, was detained in Bengaluru when he and many others defied prohibitory orders to protest against the CAA.
He was removed by some police personnel and led to a nearby vehicle.
