Killer broke down in tears after the man he stabbed 12 times died

Life sentence: Francisco Roselli will serve a minimum of 15 years in prison.STV

A man who stabbed another man to death in an apparent revenge attack has been jailed for life.

Francisco Roselli stabbed William McKenzie in the heart after chasing the victim through the streets of Knightswood, Glasgow, in November 2011.

Roselli was convicted of murder in April despite claiming he had been acting under provocation.

It emerged the 31-year-old was awaiting sentence for a separate assault charge at the time.

At the High Court on Monday, Judge John Beckett QC ordered him to serve a minimum 15 years in prison.

The judge told Roselli that he had been involved in a "vicious and sustained attack".

The court earlier heard claims that Roselli had been assaulted by Mr McKenzie and pursued the 56-year-old at around 1pm on November 15, 2011.

The stabbing in Rotherwood Avenue, Knightswood resulted in Mr McKenzie suffering 12 wounds.

Roselli then left his victim — who had been struck in the heart — lying bleeding in the street.

Roselli's lawyer told the court that his client "broke down in tears" when he learned Mr McKenzie had died.

Maurice Smyth, defending, continued: "There was no history of trouble between them. They had a friendly relationship — one that he would expect no trouble."

Judge Beckett said he accepted Roselli had shown remorse.

However, he told Roselli: "The infliction [of a knife] on the head and body demonstrates a vicious and sustained attack on William McKenzie whose loss has caused real grief — particularly to his elderly mother."
