An ATS official said on Wednesday that the Gujarat Anti-Terrorist Squad raided a manufacturing unit on the outskirts of Vadodara and seized a large cache of the banned MD drug worth around Rs 500 crore.
The ATS apprehended five people during the raid at the small factory-cum-godown near Vadodara on Tuesday night, he added.
According to the official, preliminary investigation revealed that the accused were producing the MD drug, a narcotic substance, under the guise of legally manufacturing chemicals.
The operation to break up the entire network is still ongoing, he said.
The ATS earlier this year seized more than 200 kilogrammes of the party drug mephedrone worth nearly Rs 1,000 crore from a warehouse near Vadodara.
