The Indian Navy said on Wednesday it is analysing the leak of data related to Scorpene submarines, adding that the source of leak is not from this country.
In an official statement the Navy said: "The available information is being examined at Integrated Headquarters, Ministry of Defence (Navy) and an analysis is being carried out by the concerned specialists."
"It appears that the source of leak is from overseas and not in India," the statement said.
Sensitive data related to India's Scorpene submarines has been leaked, a report in the Australian media revealed, with French shipbuilder DCNS, which designed the submarine, facing a leak of documents spread over 22,000 pages.
The report also said DCNS "implied" but did not say directly "that the leak might have occurred at India's end, rather than from France."
