The investigation into the murder of a young prostitute is being scaled down as police release a man held for questioning in the case.
Michelle Bettles had been strangled
Norfolk Police said a 30-year-old Norwich man arrested earlier this year as part of the inquiry into the murder of Michelle Bettles has been released from his bail.
Miss Bettles, who was 22 when she died in March 2002, was found strangled in woods near Dereham in Norfolk.
Norfolk Police said the investigation into her death remains open, but the number of officers on the case is being reduced.
At its height, 35 officers were dedicated to the murder investigation.
Detectives were keen to trace her trademark leather coat which was missing from the crime scene, and police are still eager to hear from anyone with information about Miss Bettles' last days.

Detective Inspector Dave Ward said: "We are still appealing for witnesses or information relating to Michelle's death.
"Our enquiries are very much led by information from members of the public, and we are therefore urging anyone with even the slightest detail to contact us.
"Callers will be treated with the utmost sensitivity and discretion. If you think you know something, however seemingly trivial or minor a detail, please contact us."
Ms Bettles was the fourth prostitute from Norwich to disappear or be murdered in 10 years.
