Police in the US state of California say they have cracked a decades-old serial murder case.
They have arrested a former policeman they believe is the so-called Golden State Killer, a serial rapist and murderer in the 1970s and 80s.
The unsolved crimes of the Golden State Killer became the subject of intense interest following publication of a bestselling book on the case earlier this year.
