A former chef has been convicted of murdering his boss 39 years ago.

Riasat Khan stabbed Kazi Ahmad to death at their shared flat on Rosemount Viaduct in Aberdeen in October 1978.

Khan was working as a chef in the Raj Dulal Restaurant when he attacked Mr Ahmad, stabbing him in the neck and body.

He then boarded train to Edinburgh, where he spent large amounts of money in a betting shop.

Khan fled to Greece before travelling home to Pakistan but returned to Britain in the 1990s and settled in Cardiff.

He was detained at Birmingham Airport in May 2016 after police discovered an arrest warrant issued in 1978 was still outstanding.

Investigators found forensic evidence linking him to the killing and the 63-year-old went on trial in Edinburgh last month.

He said he had acted in self-defence because his victim had lost his temper and claimed Mr Ahmad wanted him to perform sex acts on him.

Police and prosecutors were unable to find any evidence of a sexual motive for the crime.

Following his conviction on Wednesday, judge Lord Beckett deferred sentence to allow the court to obtain reports about Khan's character.

He told the jury he was keen to find out why it has taken so long for Khan to be brought to court for the matter.

Lord Beckett added: "I want to know why it has taken 39 years for this matter to court and why this person has been living in unconstrained freedom for long.

"I want to know as much as possible before I impose sentence in this case."

Khan will be sentenced on November 24.
