A 25-year-old man who was arrested on suspicion of murdering Hull University student Libby Squire has been released under investigation.

Miss Squire, 21, disappeared in February this year, leading to a search which involved hundreds of police officers and members of the public.

But, after being missing for nearly seven weeks, the philosophy student's body was recovered from the Humber Estuary in March.

On Wednesday, Humberside Police revealed that a man had been arrested on suspicion of murdering the student, who was originally from High Wycombe.

But, in a statement issued on Thursday, the force said: "The 25-year-old man arrested yesterday on suspicion of the murder of Libby Squire has been released under investigation as further inquiries continue."

Detective Superintendent Martin Smalley added: "Proceedings are active and I would remind people to please refrain from any speculation, as the investigation is very much live and continuing.

"There are further inquiries still being carried out and there are constantinvestigative developments and procedures that are ongoing.

"The majority of the additional analysis stage is now complete, with a smallnumber still pending final results. A file is being prepared for the CrownProsecution Service as the investigation progresses."

He said: "My heartfelt thanks go out to Libby's parents for their continuedunderstanding and patience.

"They have been kept informed of all the developments in the investigation and they will always maintain our support."

Miss Squire was last seen at around 12.09am on February 1 near her home on Wellesley Avenue, Hull, having returned home from an evening out.

Later that morning, she was reported missing, prompting an intensive search by hundreds of uniformed officers as well as search specialists, dog handlers, underwater officers and the public.

At one stage, around 200 students gathered in the rain as a show of solidarity and support for the student and her parents.
