A chilling postcard detailing a sickening crime is up for auction next week for up to £1000 - because experts say it was written by 'Jack the Ripper.'

Historical experts have validated the postcard, which was once used as police evidence in 1888 in an attempt to capture the brutal slayer.

Written on the card is: “Beware there is two women I want here they are bastards, and I mean to have them with my knife is still in good order it is a students knife and I hope you liked the half of kidney. I am Jack the Ripper.”
