During the search police personnel recovered Bangladeshi currency from their possession. After the preliminary investigation, they admitted that they entered into the Indian territory in Tripura by illegally crossing the border with the help of Indian touts.We launched a hunt to track down the ‘Agents’ who are facilitating the infiltration of the people from Bangladesh. The agents locally known as ‘Linemen’ are active in specific border areas marked for the intrusion from across the border. The places are fenced and guarded, but the ‘Linemen’ have the access and the ability to transfer the people through safe corridors in lieu of money. Most of the infiltration bids occurred during the night and the Agents arranged ladders on both sides of the fencing to smuggle men and women who pay for the service, said the police officer.
