New Delhi, Sep 19 (IANS) The Central Bureau of Investigation (CBI) Tuesday attached properties of Ravi Shankaran, who is allegedly involved in leaking sensitive information from the Indian Navy war room.

Shankaran's properties in Goa and Pune were attached after he failed to appear before a court, CBI officials said.

The investigating agency had earlier asked Interpol to issue a red corner notice against Shankaran, a close relative of Indian Navy chief Admiral Arun Prakash and had revoked his passport.

Shankaran, a retired naval officer, is believed to be in London.

Shankaran, along with nine others, is accused of stealing sensitive data in what is known as the Navy War Room leak case.

The CBI had earlier issued a non-bailable arrest warrant against him after he failed to appear for questioning despite several notices.

The CBI had also raided the offices of his company Shanks Oceanographic Private Ltd in Mumbai and Goa and recovered sensitive documents.

During the investigations, retired naval commander Kulbushan Parashar, who was arrested by the CBI, told investigators that he had met Shankaran in London.

The CBI arrested Parashar April 6 when he returned from Britain. The agency had also issued a notice against him.
