New Delhi: Senior CPM leader and Tripura Chief Minister Manik Sarkar on Monday came down hard on the Home Ministry accusing it of taking a number steps including on proposed NCTC and RPF and BSF Acts which have "serious implications" for the federal structure of the country.

Speaking at a conference of chief ministers on internal security, the lone communist Chief Minister cited Home Ministry's notification to form the National Counter Terrorism Centre (NCTC) and proposed amendments to the RPF Act and BSF Act as examples of "encroachment" upon rights of the states.

"I am pained to point out that in recent past the Home Ministry has taken several steps which have serious implication for the federal structure of the country," he said.

Opposing NCTC notification and proposed amendment to the RPF Act and BSF Act, he said the tendency to take actions in "breach of federalism" have caused serious apprehension among the states.

"It is no surprise that so many state governments have expressed their concern on the tendency of the central government to take action in breach of federalism which pervades throughout our constitutional scheme," Sarkar, who in serving his third consecutive term, said.

On NCTC, he objected to the creation of a separate operation wing and conferring it with power of arrest and search under provisions of the Unlawful Activities Prevention Act in respect of any offence committed in a state.

"Arming intelligence agency, which are not accountable to Parliament or courts, with such powers may have undesired consequences," he said.

On the security situation in Tripura, Sarkar said a number of militant outfits are operating in the state from across the border in Bangladesh and asked the Centre to take up the issue with the neighbouring country.

"The extremist organisations are mainly operating from across the border in Bangladesh. Details of locations of their camps and activities in Bangladesh have been shared. The issue should be taken up with the Bangladesh," he said.

There are "enough indications" of plans of militants to strike at security forces, he said, adding Bangladesh government should be requested to hand over "front ranking" cadres of the outfits to India and cease their bank accounts.

Seeking better vigil on the border with Bangladesh, he asked the Centre to complete fencing of the remaining 175 km of the 856 km long border with the neighbouring country expeditiously, besides ensuring better illumination there.

Referring to Bangladesh Prime Minister Sheikh Hasina's visit to Tripura in January, Sarkar hoped for better economic engagement between the two sides, noting that settlement of issues relating to trade, access to railway network of the country and use of Chittagong port would fundamentally alter the economic situation of the region.

On the security situation, the Chief Minister sought permission of the Home Ministry to raising two more India Reserve Battalions in the state apart from assistance in improving intelligence gathering capability of police.

Raising the issue of 36,000 Reang refugees in Tripura, he sought Centre's intervention in repatriating them to Mizoram from where they had come to the state 14 years ago.

He also sought Centre's intervention in handing over of 123 acres of land which is under "occupation of the Assam Riffles" at Agartala to the state government.
