Oldest criminal mugshots 'in the world' uncovered

The photos were taken by the deputy governor of Derby Gaol of some of the region's most hardened criminals.

They feature the leader of a "cracksmen" (burglars) gang, a 24-year-old who had been imprisoned 12 times and a young expert pickpocket.

Richard Felix spent 12 years tracking down the photos and says he still wants to find the original album.
