Detectives investigating a street robbery on High Street in Bromley, are appealing for help to trace the two victims.
At around 13:00hrs on Saturday, 27 January, three males wearing balaclavas approached the two victims before searching their pockets and stealing cash.
The robbery was caught on CCTV, and an operator was able to guide police to the suspects who were arrested nearby a short time later on suspicion of robbery.
The three suspects - aged 14 [A], 12 [B] and 13 [C] - were questioned and subsequently bailed until a date in mid-February.
The victims were not present at the scene by the time officers arrived and could not be located after the incident; officers would like to speak to them about the robbery.
They are described as being white boys, aged 12 or 13 years old.
Detective Constable Lorraine Robinson, the investigating officer from the Bromley Robbery Squad, said: "Officers responded quickly to this report and arrested three suspects for this robbery within an hour of the offence being committed, but we have not been able to locate the victims. We would urge them to come forward - we would just like to speak to you and get an account of what happened."
