POLICE are still appealing for information after a 15-year-old had his iPhone robbed at knifepoint on a train between Erith and Abbey Wood.

Officers have re-released CCTV images of two men they wish to speak to regarding the incident, which happened on May 8 around 6.30pm.

Police say one man was sat behind the victim and was shortly joined by another who produced a knife.

The men, who boarded the train at Slade Green and left at Charlton, searched the victim’s school blazer before stealing his iPhone.

Investigating officer Detective Constable Carole Holmes said: "This was a cowardly attack on a young boy who had no chance of defending himself against two men, while the fact that he was threatened with a knife left him understandably shaken."

Anyone with information should contact British Transport Police on 0800 40 50 40 or Crimestoppers on 0800 555 111.
