An alleged cadre of the underground Dimasa National Liberation Front (DNLF) group was arrested at Hatikhali in south Assam's Dima Hasao district.
The militant, identified as Son Khelma, was nabbed yesterday when he came to collect extortion money from a bank in the area, police sources said today.
The DNLF had about four years ago abducted at gun-point four surveyors for a Chennai-based private company from Khelma Basti village under Langting police station of the district.
The four were rescued by extremists of another insurgent outfit Dima Halam Daogah (Jewel faction) after an encounter between the two groups and handed over to the police.
