The prime accused of the Guwahati-Puri Jagannath Express bombing at Bhatkuchi between Rangiya rail junction and Ghagrapar railway station in Assam's Kamrup district last Sunday was arrested by a joint team of police and the army on Friday night.
Silva Orang, who has been arrested, is the self styled deputy commander in chief of Adivasi People's Army (APA), the militant outfit responsible for blast on the railway track.
"We suspect he had major role in the blast on railway track at Bhatkuchi. Interrogations are on. We are looking at other aspects of the blast," said AJ Baruah, SP of Kamrup district.
The APA leader was nabbed from Uttar par area along the Indo-Bhutan border in Bask district of the state.
The arrested Adivasi militant was hiding in the areas after security forces launched massive manhunt once Ape's handiwork in the blast was clear. Police earlier nabbed three other APA cadres involved in the blast at railway track.
The blast on railway track caused derailment of eight bogies from the track and four bogies fall on paddy filed. 77 people were injured in the incident.
