Two men who killed a teenager in a "brutal" street attack have been jailed.

Sean Banks, 18, was stabbed through the heart by Paul Kane in Uddingston, South Lanarkshire, in September last year.

Kane, 25, was convicted of murdering Mr Banks following a trial in August, while co-accused Liam Donnelly, 19, was found guilty of culpable homicide on an art and part basis.

The murderer, who has 16 previous convictions, mostly for violence, was jailed for life at the High Court in Edinburgh on Tuesday.

Judge Lord Armstrong told him he would have to serve at least 17 years before he would be able to apply for parole.

Donnelly was ordered to be detained for nine years at a Young Offenders Institution.

Passing sentence, Lord Armstrong said the assault had been "vicious" and he had no other option but to impose custodial sentences.

He added: "There is nothing that I can say which can compensate the family and relatives of Sean Banks for their loss.

"There is also no sentence which I can impose which will be sufficient in their eyes.

"However, there is only one sentence which I can impose in these circumstances."

The High Court in Glasgow heard how the pair acted after a 16-year-old girl alleged Mr Banks had hit her. The court heard how she said she wanted Mr Banks battered.

The two men obliged and attacked their victim, of Viewpark, Uddingston.

Jurors earlier heard how she had called Donnelly asking him to "batter" Sean. She also went on to speak to Kane during another call.

In evidence, the 16-year-old said: "Paul asked if Sean had any weapons on him. I said someone earlier mentioned he had a knife - Paul said, 'I have a bigger one'."

She said she thought Kane was only joking but he later called back and told her: "That's it done."

The trial heard Mr Banks was stabbed four times after being confronted on September 12, 2015.

Kane insisted he did not strike the teenager deliberately, adding: "I can't remember stabbing him."

He added"I didn't mean for him to die. He kept coming at me."

Prosecutor Iain McSporran branded the killing "a brutal, unprovoked multiple stabbing."

On Tuesday, Kane's advocate Mark Stewart QC told the court that his client had displayed "insight" into his actions against Mr Banks during his interview with court appointed social workers.

He added: "He appreciates the gravity of the offence to which he has been convicted of and I would ask your lordship to exercise whatever leniency is available.

"Mr Kane knows a custodial sentence is inevitable."

Donnelly's lawyer Tony Graham told the court his client also accepted that he would be sent to prison. He also told the court Donnelly had a good work and educational record.

Mr Graham added: "He has contributed to society as opposed to having been a burden on society."

The two accused were also convicted of assaulting another boy at earlier proceedings.

Kane was given two years for this offence whilst Donnelly was given three years.

Both sentences will be served concurrently with the terms imposed for the death of Mr Banks.
