A killer inflicted a fatal knife wound on the arm of a friend when violence broke out after an argument.
Dawid Majewicz, 43, struck his victim, Jacek Dembinski, with a kitchen knife after claiming he was hit on the head with a bottle during the row.
Mr Dembinksi, 44, was later seen to collapse, with blood pouring from him, outside the block of flats in Aberdeen where Majcewicz lived.
Despite undergoing emergency surgery, the victim later died at Aberdeen Royal Infirmary, the High Court in Edinburgh heard.

Majewicz was originally charged with murder following the fatal attack, which carries a mandatory sentence of life imprisonment, but pleaded guilty to the lesser offence of culpable homicide when he appeared in court today.
A judge adjourned the sentence on Majewicz until next month for the preparation of a background report to get more information on the killer.
Lord Scott told him: “Clearly, it remains a very serious matter, albeit the charge is one of culpable homicide rather than murder. You should return prepared for a significant custodial sentence on the next occasion.”
Majewicz, a car valeter from Aberdeen, admitted assaulting and killing Mr Dembinski on August 27 last year.

He struggled with his victim, struck him on the arm with a knife and failed to summon emergency medical aid for the victim.
Advocate depute Louise Beattie said Majewicz, who was born in Poland and moved to Scotland in 2008, has three previous convictions for violence, including a serious assault.
She said he was seen with his victim in an Aldi store buying what appeared to be a large bottle of vodka prior to the fatal attack. Mr Dembinski, who was also originally from Poland, had told a neighbour that he was going to his friend’s home.
They were seen together in a lift at Rosehill Court before going into Majewicz’s flat in the block. The prosecutor said that a neighbour subsequently heard sounds of an on-and-off disturbance coming from the flat.
