[5] 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.
[15] The theft was so significant that the investigation was assigned to the Flying Squad, a branch of the Specialist, Organised & Economic Crime Command within London's Metropolitan Police Service.
[16] On 8 April, press reports emerged speculating that a major underground fire in nearby Kingsway may have been started to create a diversion as part of the Hatton Garden burglary.
Some of the people who had lost their diamonds and gold in the haul tried to explain that they kept their goods there purely for safe keeping and not to hide them from tax authorities, ex-wives or the police.
[28] On 19 May 2015, 76-year-old Brian Reader, who had previously been involved in laundering the proceeds of the Brink's-Mat robbery, was arrested in connection with the burglary by Flying Squad officers.
[27][32] On 9 March 2016, at Woolwich Crown Court, three members of the gang, John "Kenny" Collins, Daniel Jones, and Terry Perkins, having pleaded guilty to conspiracy to commit burglary, were each given a seven-year prison term.
Carl Wood and William Lincoln were found guilty of the same offence and also one count of conspiracy to conceal, convert or transfer criminal property, after trial.
[41][42] The burglary is the subject of television, radio, and feature films: Some jewellers have claimed that the heist has actually helped their business due to increased publicity to the area.
