"The Thai capital is a hiding ground for several militant leaders from the Northeast. Top leaders of the National Socialist Council of Nagalim (Isak-Muivah), Ulfa and the Jewel Gorlosa faction of the Dima Halam Daogah (DHD) reside there - at times shuttling between Malaysia, the Philippines and Thailand - and co-ordinate operations back home from there," sources added. Ahmed also said ULFA leader Anup Chetia, serving a sentence in a Bangladesh jail at present, was not being extradited because of legal hurdles. India's request for Chetia's deportation has been pending with Bangladesh since 2005, after he completed a seven-year sentence in jail.
He said, "BSF is seeking a positive response from Dhaka regarding handing over of the listed Indian criminals and insurgent leaders."
India has given Bangladesh a list of 117 camps of North-East militants operating in that country and list of seven wanted Bangladeshi criminals.
Ahmed said, "There was a sea change in the tone and tenor of Bangladesh on insurgency in India. Insurgency in the Northeast is a threat to Bangladesh."
"When there is smuggling of arms and criminal activities in the Northeast, some of it will spill over to Bangladesh. An insecure Northeast India is not good for us and Bangladesh will not condone such activities," he added.
The number of camps on the list provided last year has come down from 141 to 117 camps. Most Indian insurgent groups operate from their camps in the Chittagong Hill Tracts.
