The seized North Korean ship does not seem to have any trace of chemical, biological, radioactive or nuclear material, the report of two nuclear scientists who carried out preliminary investigations at Port Blair suggests.
In their preliminary investigations at Port Blair, team of nuclear scientists from Kalapakkam has ruled out existence of any "CBRN (Chemical, Biological, Radioactive and Nuclear) traces" from the ship.
The security agencies however want a thorough investigation of the North Korean ship 'M V Mu San' by bringing her to Kakinada port in Andhra Pradesh to find out whether there was any CBRN consignment.
The exhaustive searches will again be conducted with the help of more sophisticated equipment after offloading entire 16,500 kilograms of sugar from the ship, an official, who did not wish to be named, said.
Meanwhile, the Port Blair police are yet to send their report about the entire incident.
The Centre on Thursday sent a stern letter to the Port Blair police asking them to file their report about the entire chain of events which led to the interception of the Ship and on investigations into the matter.
The North Korean vessel dropped anchor off Hut Bay island in the Andaman islands on August six without permission and was detained by the coastguard after an over six-hour chase.
The ship's 39-member crew which also includes a North Korean government official will also be questioned at the Kakinada port itself, official sources said.
The questioning of the crew got delayed due to non-availability of a Korean interpreter, they said, adding this was a unique ship where none was fluent in English. A lady interpreter had been dispatched by Ministry of External Affairs.
During the initial round of questioning of the Captain, which was made possible with the help of a local interpreter in Andaman and Nicobar Islands it emerged that the ship, carrying 16,500 metric tonnes of sugar, was on its way to Iraq after loading in Thailand, they said.
The Captain, who spoke in broken English, reportedly said the ship had developed a technical snag and that he had to change the piston besides carrying out some other mechanical work. The crew was instructed by their handlers to wait for fresh instructions before leaving the Indian waters.
