These details also include positions of aircraft and missiles. The special focus of these leakages, according to reports, are the areas around Twang in Arunachal Pradesh.
Government sources say not the Chinese government, but the Chinese intelligence agencies might have approached the NSCN(IM) through some front organisations for these details.
But the story doesn't end here.
The NSCN(IM), which has been engaged in peace talks with the Indian government for the last 15 years, has reportedly given approximately 700,000 US dollars for weapons. This points to the fact that while the peace talks are going on, they are arming themselves.
When the Indian negotiators took up the matter with NSCN(IM), they agreed to buying the weapons but said those arms have not been brought into India yet.
