Police investigating the murder of Joanna Yeates are preparing to question registered sex offenders about their movements on the night she went missing.

Up to 20 men who have a history of attacking women are to be interviewed by officers as part of inquiries into the 25-year-old's death.

Avon and Somerset Police have said there is no evidence Miss Yeates was sexually assaulted, but they have not ruled out a sexual motive.

On Friday night, officers retraced Miss Yeates' journey after she was last seen alive and questioned hundreds of witnesses in an attempt to find further information.

They spoke to customers in the pub where she went for a Christmas drink, talked to people in the streets close to her Bristol home and stopped cars where her body was found.

After leaving work on December 17, the landscape architect went to the Ram pub in Bristol city centre with her colleagues from BDP.

Miss Yeates spent around two hours socialising before leaving at about 8pm to make the 30-minute walk home to her flat in Canynge Road, Clifton.

She was spotted on CCTV in a Waitrose supermarket, at the Clifton Triangle, and then went to a Tesco Express in Clifton village, where she bought a pizza.

Detectives said Miss Yeates had made it home because her shoes, coat, mobile phone, purse and keys were found there - although the pizza, the wrapping and its box are still missing.

Her snow-covered remains were found on Christmas morning along Longland Lane, in Failand, North Somerset. She had been strangled.

Detective Chief Inspector Phil Jones, during the operation on Friday night, said: "We are hoping this high-profile activity will jog people's memories and may prompt more members of the public to contact us."

The police investigation was first launched after Miss Yeates' boyfriend Greg Reardon, 27, returned to Bristol from a weekend in Sheffield on December 19 and reported her missing.

Meanwhile, Bristol City football players in today's match against Sheffield Wednesday will be wearing T-shirts offering a £50,000 reward for information leading to the capture of Miss Yeates' killer.
