"The main reason for current situation is due to rampant illegal immigration... There have been reports of such migration to Bodoland area also. If migrants gain upper hand, locals would be apprehensive and agitate," BJP national General Secretary Vijay Goel told reporters here.
Goel, who is here leading a delegation of party leaders which will visit the disturbed areas, demanded immediate steps to prevent entry of illegal migrants.
"The government should seal the border with Bangladesh. Besides, it should also take up work for immediately updating the National Register of Citizens (NCR) to detect and deport illegal immigrants," Goel said.
He accused the state government of failing to take preventive actions.
"The situation would not have deteriorated to this extent if the state government had taken prompt action and sent additional forces on time to the disturbed areas," Goel said.
The BJP leader asked the central government to intervene in the matter.
