He also noted that the situation in southern cities was returning to normal.
Since the issue of exodus of Northeastern people from south Indian states following the recent Assam violence was of a "sensitive nature", precautionary measures have been taken in the state to avoid misunderstanding between and amongst communities, the minister said.
Police posts have been asked to remain alert with hundreds of students and professionals arriving home, he said.
Official sources said it was necessary to take extra precautions though those returning home were unlikely to create any problem in the region.
Gaikhangam said the state government would assist the family of 21-year-old Manipuri student Md. Sarif Ahmed, who was among six persons thrown out of a running train from Bangalore to Guwahati by unidentified people near New Jalpaiguiri in West Bengal.
Ahmed's body arrived here yesterday.
Meanwhile, prohibitory orders under section 144 Cr P C were imposed throughout Thoubal district where there is a sizeable population of Muslims, official sources said.
