Sonitpur, Dec 30 (ANI): Police in Assam arrested a suspect behind coordinated militant attacks on tea plantation workers and their families that killed at least 80 people, the deadliest in years. The suspect has been identified as Suklai Basumtari, who is accused of having links with National Democratic Front of Bodoland (NDFB). Police believe that a faction of NDFB, fighting for a separate state for ethnic Bodos, was behind the attacks. Police arrested him from Biswanath Chariali town in Sonitpur district under operation named, 'All Out'. Meanwhile, several media groups appealed people to donate relief materials to victims in relief camps in Kokrajhar and Sonitpur. Some militants may have fled to neighbouring Bhutan while their leader was believed to be in Myanmar, officials and police said, prompting calls for cooperation.
