The 16-year-old, who had been working as a prostitute in Norwich's red light district, was found by a lorry driver at Ringland Hills at 3.50am on Thursday, November 20 1992.

She was last seen alive in Rouen Road, Norwich, at 1.15am on the same day.

A post mortem examination revealed she had died from asphyxiation.

The case remains unsolved but police have been 'encouraged' by the initial response to a fresh appeal by Norfolk and Suffolk's Joint Major Investigation Team which so far prompted about 15 calls including some new names.

A spokesman said: 'We've had about 15 calls, a number of new lines of inquiry and some new names that we will be looking into.

'We're pleased with the response and will be following up these lines of inquiry.'

The new information follows a renewed appeal launched on Monday - the 25th anniversary of the discovery of Natalie's body on the outskirts of Norwich.

Detective Chief Inspector Caroline Millar, who leads the cold case team within the MIT, said: 'Natalie's murder is one of those cases that could be easily solved with one piece of information.

'There are people who know or strongly suspect who was responsible and I'm sure that plays heavily on their conscience. All we need is a name and we will do the rest, it is a simple matter of matching DNA. Natalie was little more than a child when she was murdered and her and her family deserve that this case is resolved.'

At the time of the initial investigation, a DNA crime profile was obtained and loaded onto the national DNA database.

More than 4,000 people have been interviewed as part of the investigation with a large number providing samples for DNA testing.

But despite advances in DNA profiling over the years there has been no match to date.

The investigation has never been closed and has been subject to reviews since 1992.
