Jack the Ripper's letter 'From Hell' and pans Dennis Nilsen used to boil his victims' flesh:
Police exhibits from some of the grisliest crimes to go on display to the public for the first time


It has been one of the most macabre and inaccessible museums in the world for almost 150 years.

From the infamous 'From Hell' letter reportedly written by Jack the Ripper to the battered old cooking pot used by serial killer Dennis Nilsen to boil his victim's flesh, it houses exhibits from some of Britain's most notorious murderers and criminals.

Now a selection of the 20,000 exhibits is set to go on display to the public for the first time.
