A suspected linkman of the banned ULFA (Independent) militant outfit was injured in police firing when he "tried to escape from custody" in Assam's Tinsukia district, an officer said on Sunday.
The suspected linkman was arrested in Jorhat recently, and based on information provided by him, a search operation was carried out in Mamoroni village in Tinsukia district on Saturday.
During the search operation, a cache of explosives, including eight PEKs (plastic explosive kirke), a detonator and six batteries, were seized and two people were arrested, he said.
