UK officials feared the mastermind behind the £26.5M Northern Bank robbery would vanish, and he remains uncaught.

British officials in 2005 feared the mastermind behind the Northern Bank robbery, one of the UK’s largest cash heists, would evade capture due to his ability to disappear, according to newly released documents. The robbery, which involved £26.5 million, remains unsolved, and authorities believe the key suspect had significant resources and connections to avoid detection. The individual, described as a "top man" in the operation, has never been formally charged.
