In a major setback to ULFA, its top leader Arabinda Rajkhowa has been detained in Bangladesh and is likely to be handed over to India soon. Another top northeast insurgent leader of banned National Liberation Front of Tripura, Biswa Mohan Deb Barma has also been detained by the authorities in Bangladesh. PTI quoting top government sources said 53-year-old Rajkhowa was picked up by sleuths of Bangladeshi security agencies last week and kept in a secured location in Dhaka while Deb Barma was detained in the southeastern port city of Chittagong. However, the Home Secretary G K Pillai and his Bangladesh counterpart Abdus Sobhan Sikder, who is currently in India, said they do not have official confirmation of Rajkhowa's detention.<br/>
