BJP MP and former Home Secretary R K Singh today said arresting gangster Chhota Rajan was not a big job. <br/><br/>Talking to media in New Delhi, Mr. Singh said it is good Rajan has been arrested but it would be a major achievement for the government if it succeeds in neutralizing or nabbing the underworld don Dawood Ibrahim. <br/><br/>Few days back, Rajan was arrested in Bali, Indonesia. <br/>On former Pakistan President Pervez Musharraf's recent admission that Islamabad supported terror groups to carry out militancy in Jammu and Kashmir, Mr. Singh said entire world has been knowing it and now his remarks are official confirmation. <br/><br/>He said India should raise this issue in UN Security Council to declare Pakistan a state who promotes terrorism.
