Secret Documents on Royal Submarine Construction Found in Pub Restroom

An investigation has been launched in the UK after secret documents detailing the construction of a royal navy submarine were discovered in a pub restroom. According to The Sun,

"The documents, which outline the HMS Anson, one of the 'Hunter killer' submarines, were found in the restroom of the Wetherspoons pub in Barrow-in-Furness. HMS Anson is the fifth of the new Astute-class attack submarines to join the Royal Navy. The vessels can fire Tomahawk missiles and are described on the navy's site as the 'largest, most advanced and powerful attack submarines ever used in the kingdom.' The papers are estimated to be worth £1.3 billion."
