Detectives investigating the murder of a prostitute in Leeds are following new leads after a "good response" to a television appeal.
Lyndsey Bourne was last seen alive on 9 September
Lyndsey Bourne's severed leg was found six weeks ago by a walker at Woodhouse Ridge in the Meanwood area of the city.
On Tuesday, her mother Karen Pawson appeared on the BBC's Crimewatch UK to ask for information about her death.
More than 30 phone calls were received by the West Yorkshire Police incident room, a spokeswoman said.
Det Supt Bill Shackleton, who is leading the investigation, said: "The response was good and we will have to evaluate what we have got.
"I am pleased with the public's response and would encourage anyone with any more information, no matter how insignificant it may seem, to contact us."
Mr Shackleton said detectives still wanted to speak to Ms Bourne's former clients and assured them their identities would be kept confidential.
But he added: "The inquiry team are aware of the identities of a number of men which we have uncovered during the investigation that have not come forward voluntarily and we will be speaking to them."
Ms Bourne, 28, originally from Selby, had been working as a prostitute in Leeds to fund a drug habit.
Her mother described her as a "beautiful, sweet natured little baby who grew into a pretty, popular girl".
"When she first told me she had been taking drugs I was devastated... I blame the drugs for turning a bright, beautiful popular girl into a prostitute," Mrs Pawson said.
"I feel I have lost control of everything and I can't bring Lyndsey back.
"I have nightmares wondering how she died and how she suffered, and where the rest of her body is. I cannot imagine life without my daughter. We all loved her and always will."
Detectives believe Ms Bourne was last seen on Thursday 9 September, when she was dropped off in Sovereign Street in Leeds city centre by friends at around 2330 BST.
She arranged to meet up with them again at 0300 BST but never turned up.
Officers have put stickers in phone boxes across the city, appealing for any prostitutes with information to come forward.
