The Delhi Police have recovered a large quantity of explosives and an ISIS flag from the house of Mohammad Mustakim Khan in Balrampur in Uttar Pradesh two days after he was arrested in the national capital, officials said on Sunday.

An alleged ISIS operative, Khan, armed with two pressure cooker IEDs, was arrested from central Delhi's Ridge Road area on Friday night following a brief exchange of fire. A Delhi Police Special Cell team took him to his Badhiyaa Bhaisaahi village in UP's Balrampur district. One brown jacket containing three explosive packets and another blue check jacket containing four explosive packets were recovered from his house, a police officer said.
