A Scots man who brandished blade at a terrified shop assistant and later said "I'm sorry about that" has died in prison.
The Scottish Prison Service confirmed Andrew Whiteford had passed away at HMP Kilmarnock on Tuesday May 31.
The 38-year-old was jailed for life in 2015 following a string of armed robbery and prison stints, the latest involving holding a 35-year-old shop assistant up at knife point.
