The directive was issued by Secretary, Border Management, in the Union Home Ministry Susheel Kumar to agencies erecting a fence along the border in Tripura sector.
This comes weeks after Home Minister Rajnath Singh had ordered that fencing along the India-Bangladesh border in Assam be completed by June 2017. Infiltration and smuggling are major problems in Assam and Tripura.
During a visit to the northeastern state on Sunday, Kumar had held a meeting with senior officials of the state, Border Security Force (BSF) and the construction agencies to review the works undertaken under Border Areas Development Programme (BADP), besides some others.
He has directed all the agencies to complete the fencing work by March 2017, a Home Ministry statement said.
