As actor Deepika Padukone's manager Karishma Prakash failed to appear before the Narcotics Control Bureau (NCB) and did not even reply to the summon, the anti-drug agency on Monday handed over the summons to her mother and owners/colleagues of Kwan Talent Agency in Mumbai.

"It is true that Prakash has gone untraceable after being summoned for questioning," an NCB official related to the probe told IANS.
