NEW DELHI: Delhi Police was sent at least six alerts on Sunday warning of possible violence and asking for deployment to be stepped up after BJP functionary Kapil Mishra called for a gathering at northeast Delhi’s Maujpur. Clashes erupted the same evening and turned into full-fledged riots the next day, but police failed to act in time.Sources said the special branch and intelligence wing had sent multiple alerts through wireless radio messages to northeast district and the police brass. The first alert to step up deployment and increase vigil was sent after Mishra posted a tweet at 1.22pm asking people to assemble at Maujpur Chowk at 3pm to support Citizenship Amendment Act (CAA).Anticipating confrontation, the intelligence wing reportedly advised the local police to increase vigil in the area. Further alerts were sent after stone-pelting began in the area and mobs were seen gathering in colonies, sources said.Delhi Police, however, denied being lax over these alerts. An officer, who did not wish to be named, said that police took all possible measures after receiving the alert.“It was for this precise reason that a senior officer accompanied Mishra and ensured that he left the area as soon as possible. Despite efforts, anti-CAA protesters started pelting stones on Mishra’s group, which led to retaliation and subsequent clashes. However, the situation was brought under control in no time,” the officer said.However, what unfolded on Monday showed that police were ill-prepared to tackle the violence.On Sunday, Mishra reached Jafrabad with his supporters and party workers. In a speech, he gave a three-day ultimatum to Delhi Police to remove the blockade. Clashes erupted soon after he left and tension simmered in the area.“Dilli Police ko teen din ka ultimatum. Jafrabad aur Chand Bagh ki sadkein khali karwaiye. Iske baad hamein mat samjhaiyega. Hum aapki bhi nahi sunenge. Sirf teen din (Delhi Police has an ultimatum of three days. Empty out the roads in Jafrabad and Chand Bagh. After that don’t explain anything to us. We will not listen to you. Only three days),” Mishra tweeted again at 5.11pm.Mishra told TOI that the anti-CAA protesters who had blocked the road in Chand Bagh forced him to come out and protest. “They have blocked two major roads, which will restrict the movement of over 35 lakh people living in that part of the city. People cannot go to work, children won’t be able to go to schools,” he had said.
