Jaishankar Tiwari, the owner of the famous Muchhad Paanwala shop in Mumbai, has been summoned in a high-profile drug nexus busted by the Narcotics Control Bureau (NCB). He has been asked to reach NCB office today and file his statement in this case. On Saturday, the anti-drug agency had arrested a British national Karan Sajnani, a former-celebrity manager Rahila Furniturewala and her sister. NCB had recovered about 200 kg of cannabis from Karan that was imported from the US. During the interrogation, the NCB found that British citizen Karan Sajnani used to supply cannabis to Muchhad Paanwala. His famous betel nut shop is located in Kemps Corner in South Mumbai.
