Detectives are continuing to question a man held on suspicion of murdering a Sheffield prostitute more than three years ago.
Miss Hague was able to give a description of her attacker
Michaela Hague, 25, was found on waste ground in November 2001 at Spitalfields and later died in hospital. She had been stabbed in the neck and back.
Police arrested a 45-year-old man Worksop on Friday morning.
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.
