Imphal, Nov. 21 :     Arrested insurgent leader Namoijam Oken was released yesterday on parole for 40 days. The chairman of the outlawed Kanglei Yawol Kanna Lup (Oken) had secured bail on medical grounds on Wednesday. Sources said his release was delayed because of his involvement in several cases. Issuing the bail order, the chief judicial magistrate of Bishenpur district directed Oken to voluntarily report at the Sajiwa Jail on December 30. He also told the rebel leader to furnish a personal bond of Rs 20,000. Oken complained of hypertension shortly after 16 Assam Rifles personnel arrested him along with three of his comrades in Dimapur on February 20. Though he was arrested in Nagaland, the rebel leader was deported to Manipur because of his involvement in several insurgency-related cases in the state. The medical board which examined Oken stated in its report that the rebel leader was suffering from enlargement of the heart. It referred him to the All-India Institute of Medical Sciences in New Delhi for advanced treatment. The place where Oken is staying since his release is a closely-guarded secret due to security reasons. It is also not known when he will go to New Delhi for treatment. Sources said the government would not bear the expenses incurred on his treatment outside the state. Oken had been eluding arrest since jumping bail in 1994 and moving to Bangladesh. The authorities even announced a reward of Rs 1 lakh on his head. The rebel leader, who parted ways with the United National Liberation Front to form the KYKL in 1990, was finally apprehended while returning here from Bangladesh via Dimapur. He was booked under the National Security Act. Since its formation, the KYKL has split into two factions ? one headed by Oken and the other by Toijamba. The Oken faction has links with the National Socialist Council of Nagalim (Isak-Muivah), but is engaged in fratricidal conflicts with other outfits. Governor?s message: Outgoing Manipur Governor O.N. Shrivastava has thanked the people and the Press for the love and cooperation he received throughout his stay here. In his farewell message here yesterday, the Governor said he tried his best to ensure transparency in the functioning of Raj Bhavan. Shrivastava said he would not take up any other official assignment and instead devote his time ane energy to social work. He will be succeeded as Governor by former Delhi police chief Ved Marwah.
