The Narcotics Control Bureau (NCB) busted an illegal laboratory manufacturing psychedelic drug LSD in Goa and arrested the main manufacturer after seizing banned substances worth Rs 25.17 lakh, an official said on Tuesday.

Incidentally, the drug manufacturer was in contact with 1980 Olympic silver medalist swimmer S Varganova and former Russian policeman Andre, who were part of an international drug cartel busted by the NCB last week, the official said.
