The Yorkshire Ripper, Peter Sutcliffe, has reportedly been questioned for a second time by officers in connection with a string of unsolved attacks.
According to The Sun on Sunday, detectives from West Yorkshire Police have spoken to Sutcliffe in prison over seven cases which date back as far as 1964.
The 70 year old is currently serving 20 life terms for the murder of 13 women and the attempted murder of seven more.
The Yorkshire Ripper Peter Sutcliffe was allowed out of Broadmoor to visit an NHS eye clinic, according to The Sun.
The newspaper published a picture of him without handcuffs at Surrey's Frimley Park Hospital.
He reportedly shared a joke with guards during the trip. The notorious killer is reportedly undergoing tests at the eye clinic as doctors try to save his sight. Sutcliffe was jailed for life in 1981 for the murder of 13 women and attempted murder of seven others.
The son of a victim of the Yorkshire Ripper has welcomed today's decision by the Court of Appeal that a life sentence means life.
A panel of five judges ruled that those who commit the most serious of crimes can receive whole life terms and expect to die in prison.

A Court of Appeal has ruled that whole-life tariffs are legal.
A panel of five judges, headed by Lord Chief Justice Lord Thomas, will announced their decision on "life-means-life" sentences this morning.
Among those who will serve their entire sentence are 'Yorkshire Ripper', Peter Sutcliffe, who was sentenced to 30 years for the murder of 13 women in the late 70's and early 80's.
Also included is Mark Hobson, who went on a killing spree in North Yorkshire, murdering four people, including twin sisters Claire and Diane Sanderson, was jailed for life, despite entering a guilty plea, and will also serve the whole-life tariff.
The Yorkshire Ripper has claimed in phone calls to his family that he should be allowed to move to a less secure facility, allowing him to "pop to the shops" on day release.
He was taped in Broadmoor talking to his brother and claims the chief doctor at the secure hospital is blocking his move.
In the recordings, which have been released by a national newspaper, Sutcliffe - who murdered thirteen women - also goes on to complain about the psychologists who visit him.
One retired psychiatrist we spoke to today says Sutcliffe still remains a threat - thirty one years after he was jailed. Lisa Adlam reports.
The brother of the Yorkshire Ripper has revealed that he speaks to the killer every week, says he still shows no remorse, and bluntly says that he should have hanged for his crimes.
Carl Sutcliffe from Bradford hid his identity when he spoke exclusively to ITV today to highlight how so many lives are effected by the horrendous acts of one person.
He also told This Morning with Phillip Schofield and Holly Willoughby how his brother Peter did form a friendship with Jimmy Savile when the entertainer came to stay at Broadmoor.
Jimmy Savile was questioned by detectives investigating the Yorkshire Ripper murders more than 30 years ago. A senior officer who worked on the inquiry has been speaking exclusively to Calendar about it.
The Yorkshire Ripper Peter Sutcliffe's decision to launch a legal bid for a state pension has brought condemnation today. The serial killer is planning to go to the European Court of Human Rights to win the right to draw the benefit. He's currently being held in the top security Broadmoor Hospital.
