NAWANSHAHR: A Nawanshahr court has awarded life imprisonment to three Sikh youths on charges of waging war against the state. Legal experts have termed it a first-of-its-kind case where accused have been sentenced on recovery of incriminating literature and not any ammunitions or for an act of violence. The accused were charged on the basis of 'books, literature, pamphlets', which were kept by them for propaganda and inciting people to establish Khalistan. Arwinder Singh (29) of Nawanshahr, Surjit Singh (27) of Gurdaspur and Ranjit Singh (29) of Kaithal in Haryana were convicted by the court of additional sessions judge Randhir Verma on January 31 and the quantum of sentenced was pronounced on Tuesday.
