Bengal BJP leader Mukul Roy appeared before the CBI today for questioning in connection with the 2016 Narada sting operation case, a day after he skipped the agency's first summons citing "preoccupations" with party affairs; BJP President JP Nadda is currently in Kolkata for a series of public events. The original summons had been issued on Thursday after the probe agency arrested senior police officer SMH Mirza. Fresh summons had been issued on Friday.
