Police are warning mobile phone users to be on the alert after a teenager was robbed in Eastcote.

The mobile phone theft, in Field End Road on Sunday last week, is the latest example of the most frequent street crime in the borough.

It happened at 11.10pm outside Eastcote tube station, when a 15-year-old boy was approached by two teenagers.

They forced him to hand over his phone, together with a gold bracelet worth £40.

The first youth was a stocky 17-year-old black male. He was 5ft 11ins, wearing blue tracksuit bottoms and a white top. The second was white, stocky and 5ft 10ins.
