Border Guard Bangladesh (BGB) detained four youths while they were attempting to cross into India illegally through Sharialjot border area in Tetulia upazila of Panchagarh early Tuesday.
Three others escaped during the drive.
The detainees were identified as Md Hafizul Islam, 21, Md Sabbir Hossain, 15, and his younger brother Md Rahan, 13, and Md Shipon Miah, 19.
The incident took place around 5am inside Sharialjot forest near Main Pillar 440 and Sub-pillar 25 under Tetulia Sadar union.
A patrol team from Sharialjot Border Outpost (BOP) of Panchagarh 18 BGB Battalion, led by patrol commander Havildar Md Sekandar Ali, spotted seven youths trying to cross the border.
The team gave chase and detained four, while three escaped. Preliminary findings suggest the youths were attempting to cross the border in search of work.
The BGB handed the four youths over to Tetulia Model Police Station on Tuesday morning.
Preparations are underway to file a case against them under the Passport Act for illegal border crossing.
Inspector (Investigation) Abdul Malek confirmed the development, saying legal procedures to file the case are in progress.
Panchagarh 18 BGB Battalion Commanding Officer Lt Col Abdullah Mohammad Kayes said legal action was being taken against the detainees.
He added that BGB personnel remain vigilant against illegal border crossings, smuggling and drug trafficking through round-the-clock patrols along the border.
