A man is being held on suspicion of murdering a Sheffield prostitute who was stabbed in November 2001.
Miss Hague's was able to give a description of her attacker
Michaela Hague, 25, was found on waste ground at Spitalfields and died shortly afterwards in hospital.
On Friday morning, a 45-year-old man was arrested in Worksop, north Nottinghamshire, and taken to Sheffield for questioning.
Police say the arrest is not linked to an appeal for information on the BBC's Crimewatch programme on Wednesday.
Miss Hague, who lived with her partner and five-year-old son in the Pitsmoor area of Sheffield, was stabbed in the neck and back after going with a man on Bonfire Night to the secluded spot near the city centre.
Another prostitute found her in a pool of blood and called the police.
Before she died, Miss Hague was able to give a description of her attacker to a police officer who cared for her until an ambulance arrived.
A key part of the investigation was to find a C-registered Ford Sierra which was spotted close to the murder scene.
Officers have already traced and eliminated the drivers of more than 3,600 Sierras during the course of the investigation.
