Situation in the Kakoi Reserve Forest in Lakhimpur district is tense following overnight firing from across the inter-state boundary along Assam-Arunachal Pradesh.

Police said the situation has been volatile in that reserve forest under Lakhimpur Forest Range since Tuesday when Forest officials demolished some structures constructed by alleged encroachers from Arunachal Pradesh.

Following this, one platoon of security personnel was deployed in the inter-State boundary area near Kakoi by the Papum Pare district of Arunachal Pradesh to maintain law and order on Tuesday.

But in spite of that, the villagers living on the Assam side of the boundary near the reserve forest alleged that they had been fired upon from across the boundary on Tuesday night.

They also alleged that an office belonging to an NGO was also set on fire by the people coming from across the inter-State boundary.

A concrete sign post erected by Lakhimpur district Forest department was also allegedly damaged by the attackers.

Local villagers on Thursday filed an FIR at Lilabari Police outpost in North Lakhimpur over the incident.

The Lakhimpur district Forest department has carried out a demolition drive of the structures constructed on encroached land in Kakoi Reserve Forest on the Assam-Arunachal Pradesh inter-State boundary on Tuesday.

The structures were constructed by Arunachal Pradesh to be used as for the Nyokum festivities.

The structures that were razed included a grain store and toilets constructed near the Nyokum Namla at Nyokum festival ground in the Kakoi area.

Two watching huts allegedly erected by encroachers were also demolished in that drive.

The Forest department carried out the demolition drive just three days after the firing incident on the personnel of Assam Forest department in Ranga Reserve Forest in Lakhimpur district.

The intruders from Arunachal Pradesh allegedly attacked on the forest personnel.

Earlier on March 11, the Assam Forest department officials allegedly obstructed the construction of the Pradhan Mantri Gram Sadak Yojna (PMGSY) road by Arunachal Pradesh authority in Bogoli-Denka area on the inter-State boundary between Lakhimpur district and Papum Pare district.
