Evidence that missing aristocrat Lord Lucan was smuggled out of the UK to a secret life abroad has come from two new witnesses.

An ex-detective said there was a credible sighting of Lucan in Africa.

And a woman who worked for Lucan's friend John Aspinall told the BBC she arranged for his children to fly to Africa where the peer could view them "from a distance".

Lucan disappeared in 1974 after the murder of his children's nanny.

Sandra Rivett was found dead at Lucan's home in Belgravia, London.

The peer's blood-soaked car was later found abandoned in Newhaven, East Sussex.

The Metropolitan Police said any "significant" new information about her death would "be fully considered".
