Serial killer 'pure speculation' say Hull police
An arm found by a member of the public sparked a massive search
The policeman in charge of three murder investigations in Leeds says there is no evidence yet to link them.
"The only obvious and undisputed link at the moment is that these three women were all prostitutes and drug users operating in Hull and it is the people associated with prostitution and drugs that may hold the key to the deaths," he said.
Her body was cut up and parts were found over the last few days at a pumping station in Sutton-on-Hull.
On Saturday Mr Davison repeated earlier warnings to prostitutes who were continuing to operate in Hull.
"Humberside police are aware of the fear this recent death has caused amongst the prostitutes operating in Hull," he said.
"This fear is founded bearing in mind the potentially dangerous situations that prostitutes put themselves into every time they indulge in such activities."
Natalie Clubb is the third prostitute whose murder is being investigated by Humberside police.
Hayley Morgan died in May, of a heroin overdose, but police say there are still many unanswered questions surrounding her death and the case is by no means closed.
Natalie Clubb was also a heroin user and was known to be a friend of Hayley Morgan.
