oss Kemp is fronting new ITV documentary "Hatton Garden: The Inside Story".
The actor-turned-journalist and his team have investigated the 2015 heist which saw £14 million worth of expensive items stolen from the Hatton Garden Safe Deposit Company, an underground safe deposit facility located in London's jewellery quarter, by a gang of elderly villains - who had a combined age of 448 - after they drilled a hole into the wall of a vault undetected.
For the show about Britain's biggest burglary, Ross spoke to key police officers and secured the first ever television interview with Kenny Collins - the gang's lookout.
The former "EastEnders" star also incorporates unseen police surveillance footage and the gang's secretly recorded conversations in the doc to provide viewers with the most detailed account of the burglary and one of the Flying Squad's longest and most challenging operations, which culminated in the conviction of the final gang member in March 2019.
The documentary will air on ITV on Friday May 24 at 9pm and comes the day after new four-part drama "Hatton Garden" ends.
Episode one of "Hatton Garden" airs on Monday May 20 and boasts a stellar cast that includes Timothy Spall, Geoff Bell and Alex Norton among others.
"Hatton Garden: The Inside Story" is not the only documentary Ross will appear in for ITV this year.
The "Ross Kemp On Gangs" star has been granted "unique access" to Belmarsh prison in South East London for an upcoming programme that will focus on how the inmates are offered the chance to rehabilitate themselves through a variety of educational initiatives designed to help them set up their own businesses when they are released.
Ross, 54, will get the chance to speak with inmates - which include murderers, rapists and terrorists - as well as staff working at the category A facility.
