The identity of Jack the Ripper has remained a mystery for more than 130 years.
But sensational new DNA evidence points to a 23-year-old Polish barber as the likely mass killer who roamed the streets of Victorian London and murdered at least five women.
Tests by scientists on DNA samplestaken from a blood-stained shawl from one of the victims purports to show that Polish immigrant Aaron Kosminski was the killer.
Scientific evidence is now said to point to Polish barber Aaron Kosminski.
The identity was confirmed by researchers from Liverpool John Moores University and the University of Leeds who shared their findings in the Journal of Forensic Sciences, the Daily Mail reported.
They wrote: "We describe for the first time systematic, molecular level analysis of the only surviving physical evidence linked to the Jack the Ripper murders.
"Finding both matching profiles in the same piece of evidence enhances the statistical probability of its overall identification and reinforces the claim that the shawl is authentic."
The analysis provided a match between murdered victim Catherine Eddowes and Kosminski's living descendants.
In 2014, Kominski was linked to the killer when Dr Jari Louhelainen, one of the authors in this week's paper, studied the same shawl.

But his claims were rubbished by other scientists who said made he made an "error of nomenclature" in his analysis.
However, despite the revelation, critics have questioned whether the shawl is viable evidence, claiming there is no proof it was alongside Eddowes' body, and that it might have been contaminated over time.

Businessman Russell Edwards, 48, who bought the shawl at auction in 2007, contacted the university scientists several years ago.
Eddowes was one of five women murdered in 1888 in the Whitechapel area of London.
She was slaughtered on the night of September 30, 1888, in Mitre Square, Whitechapel.
Eddowes was the second woman to have died at the hands of Jack the Ripper that night - he had slit Elizabeth Stride's throat an hour earlier.
As Stride's throat was cut but her body left relatively untouched, it's thought the killer had been disturbed and made his escape before being able to finish what he had started.

He is then believed to have carried on his search for another victim, eventually coming across the 46-year-old Eddowes - tearing out her kidney, which in the infamous 'From Hell' letter to police, claimed he had eaten.
The Ripper is known to have murdered at least five women; Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, and Mary Jane Kelly, but it's widely thought he may have butchered many more.
Kosminski was a Polish Jewish immigrant who, fleeing persecution in his homeland, came with his family to England in 1881 and lived in Mile End Old Town.
