London, Apr 13 A laptop containing details of top-secret anti-terror training exercises of the Special Air Service (SAS), a special forces regiment within the British Army, has gone missing.

The British Defence Ministry admitted that the computer, which was not encrypted, vanished during a recent exercise in the UK.

It comes days after top anti-terror cop Bob Quick resigned after being caught on camera carrying documents outlining secret operations, The Sun reports.

The Signals Regiment, attached to the elite force based in Hereford, was using the laptop.

Sources claim it probably contained indepth details of training exercises or the names of the personnel taking part.

Military chiefs discovered the loss during a routine audit of the kit.

A source said: "It is very embarrassing as keeping tabs on kit is the most important part of working with the SAS."

The MoD insisted the computer only contained "unclassified" information, but has launched an inquiry. (ANI)
