Officers investigating the death of Natalie Pearman, 16, say that five men identified after a fresh appeal last year have now been ruled out as suspects, the BBC reports.

Natalie was found dead in a lay-by at Ringland, near Norwich, on November 20, 1992.

Post-mortem tests found that Natalie, who had been working as a prostitute, had been suffocated and police said there were signs of sexual activity shortly before her death.

Detectives believe DNA from the scene could be crucial, and have said inquiries will continue.

The new appeal was launched in November, and the county's chief constable Simon Bailey said he had been delighted with the response.
