AHMEDABAD: Gujarat ATS and Narcotics Control Bureau (NCB) has launched a probe into the seizure of 800 kg of cocaine worth over Rs 1,200 crore, by Sri Lankan authorities, from a Gujarat-bound ship. Authorities in Colombo found the cocaine hidden in a container of teak logs with consignment papers carrying the name of a Gandhidham-based timber trader as the recipient, said ATS sources. The trader has denied having ordered any such consignment of teak logs from anywhere.“Our team, along with NCB and Customs officials are camping at Mundra Port to investigate the cocaine seizure. This is supposedly the largest drug haul ever in South Asia ,” said a senior ATS official.According to agency sources, in the second week of December, Sri Lankan authorities had seized the contraband from an India-bound ship at Colombo port. The ship had left Ecuador on October 2, and was on its way to Mundra Port through a circuitous sea route.ATS sources said the ship was allowed to proceed from Colombo, as it had shipments belonging to other companies on board that needed to be delivered against a deadline. “Our teams with NCB sleuths are searching other containers too,” said a senior ATS official.Gujarat ATS sources said they have information that the consignment was originally of 1,200 kg of cocaine, but the Sri Lankan authorities have reported finding only 800 kg. “We suspect that the missing 400 kg could have been moved out of the container somewhere on the way,” said an ATS official.Senior ATS and NCB officials said investigations are being carried out with the help of intelligence agencies in Ecuador, Belgium, Saudi Arabia and India.
