"The attack seems to be well-coordinated and pre-planned. Police have already obtained some of the footage of the incident," Minister of State for Home Kiren Rijiju said, adding that he was in touch with Delhi Police regarding the investigation.
Asked about the repeated attacks in Delhi in which people from the northeast have been targeted, he said it was a matter of worry for the government.
A 30-year-old Manipuri man was allegedly beaten to death by a group of assailants last night in the Kotla Mubarakpur area of south Delhi.
The deceased, identified as Shaloni, was returning from a friend's place in Kotla Mubarakpur when he was intercepted by a group of about half-a-dozen men who then attacked him.
Shaloni was rushed to the AIIMS Trauma Centre where he succumbed to his injuries, police said.
Earlier this year in January, a student from Arunachal Pradesh, Nido Taniam, was found dead in his room a day after he was allegedly attacked by some shopkeepers in the Lajpat Nagar area.
