A British serial killer has served his 50th Christmas behind bars after spending more time in solitary confinement than any other criminal in the world,
Notorious killer Robert Mawdsley, 70, has now spent 50 years in a prison cell, with 45 of these in solitude, which is thought to be a world record, according to The Mirror.
The criminal, nicknamed 'Hannibal the Cannibal' following false reports he ate one of his victim's brains, was just 21 when he was locked up for the murder of 30-year-old John Farrell in 1974.
Just four years later he was put into solitary confinement after killing three people inside a prison.
