Overview
The Hatton Garden safe deposit burglary occurred in April 2015, when 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 £ million in ), of which only £4.3 million (equivalent to £ million in ) has been recovered. 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. Four other men were also tried on suspicion of involvement; three were found guilty and sent to prison, while the fourth was cleared.
Burglary
The burglars worked through the four-day weekend of the Easter Bank Holiday, when many of the nearby businesses (several of them also connected with Hatton Garden's jewellery trade) were closed. There was no externally visible sign of a forced entry to the premises. It was reported that the burglars had entered the premises through a lift shaft, then drilled through the thick vault walls with a Hilti DD350 industrial power drill.
