A killer who stabbed his best friend to death has been jailed for ten years.

Darren Riley inflicted 21 wounds on Robert Reid during the fatal assault at the victim's home on Arnage Place, in Aberdeen.

Riley, 29, was originally charged with murder but was found guilty of the lesser offence of culpable homicide at trial.

A judge told Riley at the High Court in Edinburgh that relatives of the deceased had been left "devastated" by their loss.

Lord Kinclaven said: "It goes without saying that your voluntary intoxication may help to explain the background to these tragic events but that is not an excuse."

Defence counsel Ian Duguid QC said the victim had been Riley's best friend for "best part of 14 years since they were at school together".

He said they had been drinking and taking Valium and were enjoying each other's company until violence broke out on October 26, 2016.

Riley told the court the fight began after Mr Reid "wasn't happy with something I said".

He claimed that Mr Reid punched him and cut him with a knife and he went into "fight or flight" mode.
