New Delhi, Oct. 11 -- From former chief ministers Arvind Kejriwal, Mamata Banerjee and Pinarayi Vijayan to activists Yogendra Yadav and Prashant Bhushan, Delhi Police on Saturday detained several prominent leaders who tried to reach out to Jantar Mantar despite prohibitory orders to hold a demonstration against Chief Election Commissioner Gyanesh Kumar over alleged irregularities in ongoing electoral rolls revision. AAP leaders, including Rajya Sabha member Sanjay Singh, Delhi unit chief Saurabh Bharadwaj, MLA Kuldeep Kumar, and AAP national media in-charge Anurag Dhanda, were detained near Jantar Mantar. "They have unleashed tyranny across the country. The people of the country are very angry," Kejriwal said, urging people to stage sit-ins wherever they were stopped. "That place will become your Jantar Mantar," he added. Former Delhi minister Gopal Rai was detained while protesting outside the AAP office. Former West Bengal chief minister Mamata Banerjee, along with party leaders Derek O'Brien, Dola Sen, Samirul Islam, Pratima Mondal and Saket Gokhale, staged a protest at a bus stop on South Avenue after police stopped them from proceeding towards Jantar Mantar and they were subsequently detained. In a post on X from Dwarka North police station, where she was taken, Banerjee said she and four of her party's MPs had begun a dharna at the police station. Alleging that they had been "kidnapped" and "driven around in a prison van for two hours", she said she would not return to Kolkata and would join the INDIA bloc's march on Monday. The CPI(M) also condemned what it described as "widespread repression against peaceful protesters". According to the party, its general secretary M A Baby, Kerala CM Pinarayi Vijayan, veteran leaders Brinda Karat, M V Govindan, Vijayaraghavan, K K Shailaja, P K Sreemathi, Thomas Issac, K N Balagopal, P Rajeev and John Brittas attempted to proceed to Jantar Mantar. Meanwhile, Delhi CM wrote on X, "...Why are these leaders hell-bent on taking out their frustration of non-stop defeats on the public?.......
