Talking to the media, Assam Finance and Education Minister Himanta Biswa Sarma said the state government would set up a high-level committee to probe the recent violence against the new Citizenship Act.
He said 136 cases had been registered and 190 people held for involvement in violence during the anti-CAA protests.
The CAA allows Indian citizenship to illegal Hindu, Christian, Sikh, Parsi, Jain and Buddhist migrants from Pakistan, Afghanistan and Bangladesh with December 31, 2014 being the cut-off date.
Sarma, also the convener of the Bharatiya Janata Party-floated grouping of non-Congress body North East Democratic Alliance (NEDA), said through the new Act around 5,42,000 people might get citizenship in Assam.
A section of "politically-motivated" people were spreading misinformation that crores would be settled in the state under the new Act, he added.
