Indian Navy Chief Admiral Sunil Lanba on Monday said the Scorpene data leak is being taken "very seriously" and that "mitigation measures" will be taken based on the report of a probe panel.

"Any leak of information is viewed very seriously. We have viewed the leak of the Scorpene data very seriously," Admiral Lanba said.

"We have asked DCNS (French submarine maker) to launch an urgent investigation into this. We have ourselves set up a high level committee to investigate into this. Based on the report, we will see what mitigation measures need to be taken," he said.

Asked if it was a matter of concern as the Indian Navy already has fewer submarines than its requirement, Lanba said: "The committee is analysing, it will be seen what data has been compromised and what mitigation measures will be taken."

Data leaked from DCNS that runs into over 22,400 pages, including crucial details of India's Scorpene submarine programme, was reported by Australian newspaper The Australian last week.
