The messages also revealed the pair were working for a user with the handle 'There is a Big Sun in the Sky', who arranged for them to collect up to a quarter-of-a-million pounds in cash a time. Shu and Huang were not told the identity of the person they took cash from, and were told to take a photo of a £5 note including a unique serial number.

This was passed on to the courier to allow a transaction to take place without either party know each other's identity. It meant they could not pass information about other people in the chain onto police if they were arrested.
