In April 2015, an underground safe deposit facility in Hatton Garden, London, owned by Hatton Garden Safe Deposit Ltd., was burgled.
According to official sources, the total stolen had an estimated value of up to £14 million (equivalent to £20 million in 2023), of which only £4.3 million (equivalent to £6 million in 2023) has been recovered.[1][2] The heist was planned and carried out by six elderly men who were experienced thieves, all of whom were arrested, pleaded guilty and received prison sentences in March 2016.[3][4] Four other men were also tried on suspicion of involvement; three were found guilty and sent to prison, while the fourth was cleared.[5]
