DETECTIVES investigating the murder of Lucy Royle were disappointed with the public's response to an appeal for help.

The body of 21-year-old Lucy, from Davyhulme, was found on a field close to the access road to the David Lloyd centre and driving range last Saturday morning, April 19.

A media appeal for information resulted in only a handful of phone calls to the incident room.

Police also stopped motorists and pedestrians passing through the area last Friday, in the hope that some people had taken the same journey the week previously on the Friday evening when it is thought Lucy was killed.

Det Supt Peter Minshall, who is leading the enquiry, said: "The enquiries made in the area around the Trafford centre were quite promising with passers-by telling us what they saw and we are now following up a couple of possible sightings of Lucy on the evening she died.

"However, we believe that there must be other people who were in that area last week, anytime after 8.30pm, who we have not managed to speak to.

"Despite all the coverage in the media only a handful of people called the incident room to help us catch Lucy's killer."

Police are appealing for dog walkers, joggers and drivers who were in the area on Friday April 18 to help them.

Lucy - who would have been 22 on Sunday - had left her family home on Jura Drive in Davyhulme, at 8.30pm on Good Friday.

It is thought she headed along Shetland Way, turned right into Barton Road, before going through the underpass beneath the M60.

When her body was discovered, a small, black rucksack style bag she was carrying and her phone, a pink Nokia 3410 with pictures of Bubblegum characters on it, were missing and have still not been found.

They have released pictures showing what the mobile phone would have looked like.

Det Supt Peter Minshall added: "No matter how insignificant you believe the information you have is, what you saw may be the key to catching the killer."

Anyone with any information is asked to contact the incident room on 856 4343 or call Crimestoppers anonymously on 0800 555 111.
