Detectives have released a man arrested on suspicion of murdering a Sheffield mother three years ago on bail.
Miss Hague was able to give a description of her attacker
Michaela Hague, 25, was found on waste ground in November 2001 at Spitalfields. She had been stabbed in the neck and back several times.
She later died in hospital but was able to give police some information.
The 45-year-old Worksop man was arrested on Friday. A spokesman said the man would report for bail on Monday when he would face further questioning.
Miss Hague is thought to have been working as a prostitute.
An appeal about the crime was made on Wednesday's Crimewatch programme but police say the arrest is unconnected.
They said they were acting on information received previously.
Miss Hague, who lived with her partner and five-year-old son in the Pitsmoor area of Sheffield, was seen with a man on Bonfire Night going to the secluded spot near the city centre.
