Chris Jefferies, the landlord arrested over the murder of Joanna Yeates has been released on bail.
The 65-year-old has been freed pending further inquiries after spending more than two days in custody being questioned on suspicion of killing the landscape architect, whose snow-covered body was found on Christmas Day.
Mr Jefferies, who lives above the Victorian flat Miss Yeates shared with her boyfriend Greg Reardon in Bristol's up-market Clifton area, was arrested on Thursday.
The property, on Canynge Road, lies about three miles from where the young woman's body was found. Forensic investigations continue there and a high police presence remains in the neighbourhood.
Mr Jeffries' release came hours after the 25-year-old's grieving family said they were "certain" her killer would be caught.
Detectives from Avon and Somerset Police are continuing their investigation into the murder and say they are working tirelessly to bring the culprit to justice.
DCI Phil Jones said: "Firstly I would like to reassure the public that this investigation is very much ongoing. We have a team of over 70 police officers and staff working tirelessly to bring the person responsible for Joanna's death to justice.
"The incident room has been inundated with thousands of calls from members of the public who have provided us with information. This information is being scrutinised and followed up by specially trained officers who are exhausting every lead and avenue that we are provided with."
Detectives are particularly keen to speak to anyone who may have used Longwood Lane in Failand, Bristol, between December 17, when Miss Yeates went missing, and Christmas Day, when her body was discovered there.
