Speaking at the 'anti-terrorism day' at Congress here last evening, Singh said any organisation should not take any anti-national action while demanding implementation of the inner line permit system in the state.
He said the state government was prepared to detect foreigners who entered the state without valid document but compatriots from other states could not be expelled from the state.
Singh's comment followed the recent statement of the Joint Committee on Inner Line Permit System (JCILPS) that it (committee) would prevent entry of outsiders from June 1 if the inner line permit system was not implemented to protect the separate identities of indigenous people.
Sources in the JCILPS demanded immediate implementation of inner line system like in neighbouring Mizoram, Nagaland and Arunachal Pradesh.
It had said they would prevent entry of outsiders from June 1 to 5 and outsiders, already in the state, would not be allowed to enter local areas from June 6 to 10 as a part of the series of "democratic" stirs it would launch.
JCILPS sources said they were not against outsiders but wanted a system to restrict their entry so that separate identities of the local and indigenous people could be protected.
