YOUNGSTERS with mobiles are being warned to be vigilant following a spate of thefts of the phones.

Youths are being approached by people of a similar age who ask to look at their mobiles before walking off with them.

In one incident last Tuesday, a 15-year-old boy was approached in the grounds of All Saints Church in High Wycombe at around 5pm by another boy who asked to use his phone and then ran off.

Anyone with information should call town centre officer, PC Bayliss on 01494 465888.
