NORTH LAKHIMPUR, AUG 10 (PTI): At least 12 people from Assam were injured in alleged firing by miscreants from Arunachal Pradesh along the interstate border in Dhemaji district on Monday over encroachment of land, police said. The clash erupted following a dispute in connection with alleged encroachment by people from Arunachal Pradesh over land in Assam, police said. The Assam government had on July 29 told the state asssembly that Arunachal Pradesh has encroached upon 16,144.01 hectares of land. Arunachal Pradesh was a centrally-administered region initially after Independence and became a Union Territory later, before attaining full statehood in 1987. After Arunachal Pradesh achieved statehood, a tripartite committee was appointed which recommended that certain territories be transferred from Assam to Arunachal Pradesh.
