The convicts:

GREGORY FRANKEL: Frankel was a director of Fowler Oldfield and controlled the business. He signed the contract for cash to be collected by G4S. He knew of the volume of cash being credited to Fowler Oldfield and the way it was being delivered to the premises. He collected and delivered some of the cash himself.

DANIEL RAWSON: As one of the two directors of Fowler Oldfield, Rawson was at the heart of the business and was involved in strategic decisions affecting operations. He was also physically involved in counting the large amounts of cash delivered to the premises. In addition, he was a key player in a private messaging system – Telegram – which was used to communicate passwords and the amounts of daily cash counts.

HAROON RASHID: was the sole director of Rashid Jewellers Ltd. He was a frequent visitor to the premises of Fowler Oldfield where he apparently had his own key and could use a swipe card and security code to enter the secure areas where cash was counted and to access the business’s computers.

ARJUN BABBER: He was based in London, where other members of his family ran RPS Jewellers Limited, a well-known and reputable gold and jewellery business based in West London and Hatton Garden. Babber had his own company called Goldsteel Limited and, in 2015, began to launder cash for others through Fowler Oldfield Limited.
