Agartala: A top militant leader was arrested in Tripura after he was pushed into the Indian territory by Bangladeshi authorities, police said.
"Separatist outfit ATTF's (All Tripura Tiger Force) self-styled president Ranjit Debbarma was pushed back by Bangladesh security forces at an undisclosed place in western Tripura bordering Bangladesh," a senior police official told IANS.
"The Tripura Police arrested him and started interrogation," the official said on condition of anonymity.
Debbarma, 41, was the founder chief of the ATTF and its 'political wing' Tripura People's Democratic Front (TPDF), also an outlawed group. He had carried out a number of killings.
The Tripura police had earlier declared a reward of Rs.2 lakh to know his whereabouts.
The ATTF had hideouts and training camps in Bangladesh, have been demanding secession of Tripura from India.
Top intelligence sources here said Debbarma along with his associates was picked up by sleuths of Bangladeshi agencies and kept in a secured location in Dhaka last month.
Debbarma is the most dreaded and top militant leader after the ULFA's (United Liberation Front of Assam) founding member and chairman Arabinda Rajkhowa.
Rajkhowa and his associates were also pushed back by Bangladesh authorities into India in December 2009.
Tripura's two banned militant outfits - the ATTF and the National Liberation Front of Tripura (NLFT) - have set up bases in Bangladesh.
Tripura shares an 856-km border with Bangladesh, some of it unfenced and running through dense forests and mountainous, making it porous and vulnerable and advantageous for the terrorist outfits for their cross border movements.
