The Delhi Police's Special Cell on Thursday apprehended a man in connection with the killing of Intelligence Bureau (IB) staffer Ankit Sharma during the violence last month in the national capital's northeast district, police said.
The accused has been identified as Salman alias Nanhe, they said.
Ankit Sharma's body was found in a drain near his home in northeast Delhi's Chand Bagh area on February 27, a day after he went missing.
Earlier, police had arrested suspended Aam Aadmi Party (AAP) councillor Tahir Hussain in the case.
