Snake venom valued at Rs.100 crore in the international market was seized and six people were arrested at Belakoba in West Bengal's Jalpaiguri district on Saturday, officials said.
Acting on a tip off, forest guards stopped six people on motorcycles and recovered the venom from their possession after a search, said Baikunthapur forest division ranger Sanjoy Datta.
"They were carrying school bags. After we searched the school bags, we found the venom storied in containers," he said.
Datta said probably they were smuggling the venom to Bhutan.
