West Yorkshire Police connected Swedish authorities last year in relation to two unsolved murders of Swedish women, reports newspaper Kvällsposten. 
 
 “They wanted answers to a number of questions, including whether we have the type of murder, whether forensic evidence exists and whether there is anything that can be investigated using new techniques,” Bo Lundqvist, police commissioner with the Region South Police department for cold cases, told the newspaper. 
 
 “They also wanted to know whether Peter Sutcliffe was named in any investigations,” Lundqvist added. 
 
 The two crimes that British police wish to investigate are the murders of a 31-year-old woman, who was found in Gothenburg in August 1980, and a 26-year-old woman who was found in Malmö in September of the same year. 
 
 Lundqvist confirmed to Kvällsposten that Malmö Police did in fact contact British police in January 1981, after the media in Sweden had drawn attention to the fact that Peter Sutcliffe may have been in Malmö at the time of the 26-year-old's murder.

 The Swedish police communication reportedly coincided with Sutcliffe's arrest and later conviction. 
 
 Interpol responded to Malmö Police, saying that Sutcliffe could not have been in the city at the time of the crime – information that the agency later found to be incorrect, according to the report. 
 
 According to a ferry passenger manifest, Sutcliffe was likely in Malmö at the time of the second Swedish murder. The manifest shows Sutcliffe's name on board a service between Malmö and Dragør in Denmark on the days before and after the murder in the Swedish city, Lundqvist told the newspaper. 
 
 The police officer said that this information probably never reached the British police at the time of their investigation against Sutcliffe, and subsequently the Swedish connections were not followed up. 
 
 Sutcliffe, who worked as an HGV driver and was dubbed the Yorkshire Ripper by the British press, was sentenced to life imprisonment in 1981 for murdering 13 women between 1975 and 1980. 
 
 But after opening a review of unsolved crimes last year, West Yorkshire Police told Lundqvist that they were aware of a telex from Interpol indicating that Sutcliffe had travelled on the Malmö-Dragør ferry. 
 
 Malmö Police have previously confirmed that a hair which was found on the woman's body has been preserved, according to the report. 
 
 Lundqvist responded to the British request but has not yet received any further information on the case, writes Kvällposten. 
 
 The decision to grant British authorities access to any forensic material will fall to the Swedish justice department, reports the newspaper. 
 
 Unsolved murders that date prior to 1985 are lapsed under Swedish law but not according to British legislation, Lundqvist said. ||||| A man in his 70s has been arrested on suspicion of the murder of a schoolgirl more than 50 years ago. 
 
 The police investigation into the death of Elsie Frost, 14, in West Yorkshire in 1965 was re-opened last year after a series of reports on BBC Radio 4. 
 
 Police say a 78-year-old man was held in Berkshire. The BBC understands his name is Peter Pickering. 
 
 Elsie was stabbed to death in a tunnel beneath a railway line in Wakefield on 9 October 1965. 
 
 She had been on her way home from her school's sailing club, close to the River Calder and the Calder and Hebble Canal. 
 
 A large police operation followed. The area was searched for the murder weapon, which was never found and hundreds of people were interviewed but no-one was ever convicted of her murder. 
 
 As the 50th anniversary of her death approached, her older sister, Anne Cleave, contacted BBC Radio 4's PM programme, which started to look at what had happened. 
 
 As a result, police launched a new investigation. It has involved a team of 14 and thousands of pages of written evidence have been examined. 
 
 'New information' 
 
 In a statement, West Yorkshire Police said: "Officers from West Yorkshire Police`s Homicide and Major Enquiry Team (HMET) arrested a 78-year-old man in the Berkshire area on Tuesday 27 September on suspicion of the murder of 14-year-old Elsie Frost. 
 
 "The man is now in custody at a police station within the Thames Valley force area and will be questioned by West Yorkshire officers".

 It is only the second arrest since the killing. The first was in 1966 when a 33-year-old man was charged with her murder. The case was thrown out in court after a judge instructed the jury to find him not guilty. 
 
 Reacting to the arrest, Elsie Frost's younger brother, Colin said: "As a family, we're very pleased. All we wanted was to be taken seriously. 
 
 "We were aware that mistakes were made in 1965 but we've been impressed with the commitment of West Yorkshire Police in the reinvestigation - the number of officers involved, the number of agencies involved. 
 
 "We wanted the re-investigation to be re-opened and that's what we've achieved." 
 
 Det Supt Nick Wallen, who is leading the investigation, said: "We have received significant numbers of calls and emails from members of the public offering new information, and have generated new lines of inquiry which officers have been progressing ever since." 
 
 He praised Elsie Frost's family for their perseverance and said they are being kept fully informed.
– British cops are investigating whether a serial killer locked up for nearly four decades could be behind two cold cases in Sweden. Police in the southern Swedish city of Malmö say a passenger ferry list shows that "Yorkshire Ripper" Peter Sutcliffe was apparently in the area in September 1980 when the body of 26-year-old Teresa Thörling was found dumped at a construction site, Kvällsposten reports via the Local. At the time, that murder was linked to the brutal killing one month earlier of Gertie Jensen, 31, in Gothenburg. Swedish sleuth Bo Lundqvist confirmed to the newspaper that Malmö cops told UK authorities in 1981 that the truck driver may have been in the city around the time of the murders. That lead went nowhere after Interpol reported—wrongly, it turned out—that Sutcliffe was not there. Interpol later corrected that version in a telex that apparently wasn't spotted by UK cops until last year, when a cold case squad took another look at the two unsolved murders. They have another major clue to pursue: a hair recovered from Thörling's body that could identify her killer. Lundqvist confirmed that UK cops have asked his department for help. "They wanted answers," he tells Kvällsposten, including forensic evidence and "whether Sutcliffe was named in any investigations." Sutcliffe was diagnosed with paranoid schizophrenia, per the Guardian, after being sentenced to life in prison in 1981 for the murders of 13 women in the UK in the late 1970s, and the attempted murders of seven others. Although the statute of limitations has lapsed for the two murders in Sweden, Sutcliffe could be prosecuted under UK law. (A letter reopened a very old case.)
