The United Liberation Front of Asom claimed to have blown off an oil well in Tinsukia district of Assam causing panic among the local residents on Saturday. The incident took place at Chandmari near Makum where the Oil India Limited-owned rig caught fire following a huge sound in the wee hours. No injury or casualty has been been reported so far. According to the OIL authorities, the fire was reported around 1 at midnight. Several fire tenders deployed there took nearly 5 hours to douse the blaze. Later the well was sealed. Initial investigation suggests it an attempt to steal oil from the well. The thieves made a hole in the oil well's high pressure `xmas tree' valve causing hydro carbon to come out in liquid form. It caught fire due to the difference in temperature inside the well and outside it. OIL and police were keeping a strict vigil to prevent repeated attempts at theft of condensed oil from the wells in the area. Meanwhile, ULFA’s Paresh Baruah faction claimed that they had blown off the oil well.
