Agartala, Dec 7 (IANS) Four militants, including self-styled army chief of All Tripura Tiger Force (ATTF), have surrendered to security forces in Tripura, police said Friday.
Chitta Debbarma, the 37-year-old Bangladesh-trained self-styled army chief of the separatist outfit, gave himself up to Assam Rifles personnel Thursday night.
Debbarma surrendered to the paramilitary along with his three women family members.
"The ATTF leader, who was a constable in the Central Reserve Police Force (CRPF), left the paramilitary in 1980 before joining to the militant outfit. He was wanted by the Tripura police for many crimes including killings," a police spokesman told reporters.
Police had declared a reward of Rs.two lakh for his capture.
Three more ATTF guerrillas, aged between 25 and 35, also separately surrendered to Assam Rifles Friday.
The police official said the extremists have also deposited arms and ammunition.
Tripura's two banned militant outfits - ATTF and National Liberation Front of Tripura -- have set up bases in Bangladesh and get support from other separatist outfits of the northeastern region.
They have been demanding secession of Tripura from India.
