In a joint letter to Home Minister Sushilkumar Shinde, the MPs from several states and parties sought his immediate intervention in the matter urging him to ascertain the amount of damage already done and "bringing this unnecessary backlash to a halt".
"With deep anguish, we, the MPs representing several Northeastern states, wish to bring to your notice the horrific incidents of backlash against Northeastern students in the cities of Pune, Hyderabad, Bangalore and other metropolitan cities," they said.
They urged Shinde to advise the state governments to "take firm and punitive action against the perpetrators of this violence".
