He had said that the protestors can "trust him" and there is no problem in protesting after 3 pm. In a video posted on Twitter, one of the protesters is seen asking the police officer why they were being held despite the promise made by the DC a few days ago. In reply, the police officer is purportedly heard saying that he is the local AC and he will arrest them if they continue with the protest. A crowd gathered at the community hall where the protestors were detained to demand their release. A human chain was also formed, causing a scuffle between the protestors and the police, as the latter said it was causing hindrance to public peace.
