The Mizo Zirlai Pawl or the Mizo Students' Federation claimed that its activists have detected and pushed back nearly 500 people from Assam trying to enter into Mizoram without valid citizenship documents.

The outfit's activists have started keeping a vigil on the Mizoram-Assam border following publication on July 30 of the final draft of the NRC in Assam, in which 40 lakh applicants were left out, MZP president L Ramdinliana Renthlei said.

MZP president said that activists of his organization detected and pushed back around 500 people from Assam from three checkpoints – Vairengte, Bairabi and Saiphaim between August 16 and August 30.

He alleged that the Mizoram government did not take necessary steps, though other northeastern States made arrangements to prevent "illegal migrants" from sneaking in.
