World's End serial killer Angus Sinclair has died in prison aged 73.

He was jailed for life in 2014 for raping and killing Christine Eadie and Helen Scott, both 17, in Edinburgh with his brother-in-law Gordon Hamilton, who died in 1996.

His crimes became known as the World's End murders because the girls were last seen leaving a pub by that name in the city's old town on 15 October 1977.

The pair had been bound and strangled with their underwear. Their bodies were discovered the following day in East Lothian.

Judges described Sinclair's murders as displaying "an immeasurable capacity for evil, depravity, and sadism".
