Adam Paton, 17, died after being attacked in April
A 17-year-old has been found guilty of killing another teenager in Angus.
Ross Anderson was acquitted by the jury at the High Court in Aberdeen of murdering Adam Paton, 17, but was found guilty of culpable homicide.
The court heard Anderson stabbed Mr Paton to death after a fight broke out on North Street, Montrose, in April.
Anderson was also found guilty of assaulting Craig Simpson by threatening him with a knife after the stabbing. Sentence was deferred until next month.
The judge, the Right Hon Lord Carloway, described the case as "distressing and difficult".
He told Anderson: "You have been acquitted of murder.
"However, you have been convicted of culpable homicide which is also a serious crime, taking into account the fact you used a knife in the street."
During the trial, Anderson, who had just been released from a secure unit at Rossie House near Montrose before the attack, admitted stabbing Mr Paton.
But he claimed to have taken the kitchen knife from his girlfriend's flat for his own protection.
The court was told a number of teenagers had been drinking and taking drugs at a flat on North Street before a fight broke out and Mr Paton, from Brechin, was stabbed.
Neighbours ran out of their flats after hearing the commotion and called the police.
Pc Alan Marnie, from Tayside Police, told the court he had tried to resuscitate Mr Paton for 20 minutes but he died of his injuries on the pavement.
