Detectives investigating the murder of Poole chef Glyn Helliwell who are tracing his mobile phone think it may have been sold to a shop.

Local store owners who may have bought a black Sony Ericsson k-800-i since then are being asked to come forward, as it may provide vital clues as to what happened.

The forty-two year old died in hospital after being found stabbed in the early hours of Wednesday morning, and police are also searching for the weapon used.
