"As per available information, around 3,700 such immigrants have been identified in Odisha," Minister of State for Home Kiren Rijiju said during Question Hour.
The Minister said though they have been found involved in cases of petty theft or illegal fishing, there have been no reports of their involvement in any major crime.
"Illegal migrants, when detected, are dealt with as per provisions of the law which include measures to deport them in accordance with the Foreigners Act," he said.
