The contraband was brought here amid tight security from Porbandar where it was stored after being seized by the Indian Coast Guard on July 30, NCB's zonal director Hari Om Gandhi told PTI.
The Coast Guard had termed the seizure from a merchant vessel as "the biggest catch of narcotics in the present times".
"We brought the drug here today from Porbandar. It will be kept in a safe custody with a police team guarding it round-the-clock. A high-level committee of senior NCB officials, police and the Customs among others will be formed to oversee the destruction process," Gandhi said.
NCB has obtained permission to destroy the drug as well as dispose of the seized merchant ship from a court in Porbandar. The ship will be auctioned off at the Alang ship breaking yard, Gandhi said.
NCB has so far arrested thirteen persons in the case, including eight crew members of the ship.
