Shankar, a clerk in the state road transport office in the southern suburb was arrested on Thursday and remanded to 5-day judicial custody for interrogation.
Among others booked in the FIR are Abhiswamy, Aditya Alva, son of late Janata Dal legislator Jeevaraj Alva, Ashwin, Prashant Raju, Prashant Ranka, Vaibhah Jain and Vinay.
"Another drug peddler - Loum Pepper Ssamba, a foreign national, was arrested earlier in the day and remanded to our custody for interrogation as he is alleged to distribute narcotic drugs to celebrities and others," said Patil.
Khanna is an event manager who organises big parties in this tech city and operates Bangalore Expat Club for overseas citizens, including NRIs in the city.
Shankar is said to be one of the peddlers supplying drugs to rave parties and Sandalwood industry events.
In a related development, the anti-narcotics wing of the CCB arrested 3 more drug peddlers in the city on Saturday for allegedly selling hash oil and weed oil.
