The landlord arrested over the murder of landscape architect Jo Yeates has been released on police bail.
Chris Jefferies, 65, was questioned by Avon and Somerset Constabulary after being arrested on suspicion of murder on Thursday.
Miss Yeates, 25, was found strangled on Christmas Day, a few miles from her home in Bristol's Clifton area.
Her body was found in Longwood Lane, in Failand, near Bristol, by a couple walking their dogs.
In a statement on its website, the force said: "A 65-year-old man who was arrested on suspicion of murder has been released on police bail."
Det Ch Insp Phil Jones issued a renewed appeal to the public for information.
"Firstly I would like to reassure the public that this investigation is very much ongoing," he said.
"We have a team of over 70 police officers and staff working tirelessly to bring the person responsible for Joanna's death to justice.
"I would once again urge anyone who may not have called us to make contact with one of my officers and provide us with any information you may have. You may think your information is insignificant but please let us decide."
Mr Jefferies lives in the flat above the Victorian basement property he rented to Miss Yeates and her 27-year-old boyfriend Greg Reardon.
Forensic science teams have been continuing to remove items for examination from the properties.
Miss Yeates was last seen alive on 17 December. She had been out with work colleagues and is known to have left the Bristol Ram pub, on Park Street, at about 2000 GMT.
Police have issued CCTV images of her then visiting a Waitrose store on The Triangle, a Bargain Booze shop, and a Tesco Express near her flat.
She bought a pizza at the Tesco store but while the receipt was found at her flat, no trace has been found of the food or its wrapper.
Mr Reardon reported her missing two days later when he returned home from visiting family in Sheffield.
In a fresh appeal for information Det Ch Insp Jones said all calls to the police would be "treated in confidence".
He added: "We also know that there were large Christmas functions taking place at Long Ashton golf club, Bristol and Clifton golf club and Redwood Lodge.
"I would again urge taxi drivers and those who drove to functions to call us. They may have information that could prove vital."
Miss Yeates's body was found near Long Ashton Golf Club.
