Actor Vivek Oberoi, a vocal supporter of the BJP who starred as Prime Minister Narendra Modi in an adulatory biopic, must be investigated for possible links to the drug abuse scandal being probed by the Narcotics Control Bureau or NCB, Maharashtra Home Minister Anil Deshmukh said on Friday. Mr Deshmukh's comments came after a Congress party delegation met him with the demand following a raid at Mr Oberoi's residence by the Bengaluru Police on Thursday in connection with the drugs scandal involving the Kannada film industry.
