The National Investigation Agency (NIA) has arrested one self-styled sergeant of NSCN(IM) Ellie Ketok, in connection with the murder of Arunachal Pradesh MLA Tirong Aboh in May.
The 37-year-old Ketok was arrested on Sunday from Nagaland’s Dimapur by a joint team of the terror probe agency and the Army, the NIA said in a statement.
The accused was a part of killing team, and actually fired on Aboh and others on May 21 this year.
The anti-terror probe agency had earlier arrested five persons — Sethok Kangnong, Napong Jenpi alias Jenpi, Jai Kishan Sharma, Luckin Mashangva and Yangte Josaham — in connection with the probe into the case.
The Arunachal Pradesh Government had earlierhanded over the killing of Aboh, an MLA from Khonsa West, and nine others by suspected NSCN-IM militants to the NIA.
Nationalist Peoples’ Party (NPP) MLA Aboh, his son and nine others were killed when suspected NSCN-IM militants opened fire at their vehicles near 12 Mile area in Tirap district.
The MLA along with his relatives was on his way to Khonsa from Dibrugarh in Assam when the attack was executed.
The National Socialist Council of Nagaland (NSCN-IM) is in ceasefire with the Centre since 1997 and negotiations are on to resolve the decades-old Naga issue.
A framework agreement was signed between the Centre and the NSCN (IM) in August 2015.
