The Bodo National Council and all Bodo Students' Union have publicly renewed claims for a new state last year.
Native Bodos are Assam's largest plains-habitating tribe, which runs the Bodo Territorial Council comprising four districts.
A renewed statehood demand could prove to be tricky for the Centre, which gave the Bodos administrative autonomy under the Constitution's Sixth Schedule through a 2003 accord on the condition they will give up claims for a new state.
While the Bodos have always been protective of their turf and identity, partial autonomy was seen as a solution to decades of under-development.
Bodos see the settlers, some of them generations old, as usurpers of scare resources. A fresh statehood campaign has sharpened the divide.
"We were told we would be targeted because we did not agree to the Bodos' demand that we pledge support," said Mohibur Islam, a local migrant leader whose attempted assassination touched off a deadly retaliation by migrant Muslims on July 20.
