At around 4.30pm on Monday, 22 March the girl got on a bus towards Lewisham.
When she got off the bus, she walked towards Pepys Park where she sat on a bench near the football cages.
A boy approached her. He was joined by two other boys who are alleged to have stolen her phone and ran off.

Detective Constable Daniel Weeks, who is leading the investigation, said: “We are doing our utmost to provide the victim with support from specially trained officers following this horrific incident.
“I am asking members of the public who were in the park that day to think carefully about whether you saw the males described. Did you see anyone acting suspiciously? What were they doing and where did they go? No matter how small or insignificant you think your information might be, it could be hugely significant for our investigation.”
