In an obvious reference to the arrest of his controversial MlA Anant Singh, Chief Minister Nitish Kumar on Friday said he has established rule of law in Bihar and he did not come under any pressure nor anyone was needed to be concerned.“When in 2005 I came to power I established rule of law from that very day. Before that during Nyay Yatra I made two promises to the people that I will adopt a path of development with justice and establish rule of law. Until I am here people should not feel concerned about law and order,” he said while talking to media.
