CBI is likely to register a case soon to probe alleged irregularities in purchase of high-altitude tents by Research and Analysis Wing (RAW), the country's external intelligence gathering wing.

Official sources said the CBI has received a request for a probe into the purchase of tents during 2010 by the Special Frontier Force (SFF), which was created by RAW.

The papers sent by the intelligence agency are being scrutinised and a case is likely to be registered in the coming week, the sources said.

Recommendation for a thorough probe was made by RAW to the CBI for fixing responsibilities of people involved in the alleged bungling in the purchase of these costly tents.

The decision to handover the case was taken after an internal enquiry conducted by the external snooping agency indicated involvement of some of its officials in the alleged bungling.
