An "evil and calculating" cannibal killer has been jailed for life for strangling a police officer during a bondage sex session and then cooking and trying to eat him.

A sadomasochist accused of strangling a police officer during a sex game in England has admitted being "inspired" by hit television series Breaking Bad when he tried to dissolve the body in a bath of acid.

The decomposed remains of missing police officer Gordon Semple were discovered after a neighbour alerted Scotland Yard to a “smell of death” coming from a housing estate flat.
