A TEENAGER brutally stabbed a man in the neck during a horror murder bid.

Matthew Owen, 19, struck Ali Karimi, 23, twice in Drumchapel's Rozelle Avenue and Jedworth Avenue on July 13, 2018.

Owen left the former barber scarred for life amid claims the victim had stolen his cousin's phone earlier that day.

The young thug faces a lengthy spell behind bars after being convicted of attempted murder at the High Court in Glasgow.

Jurors heard Mr Karimi was attacked after an apparent row with Owen's partner.

In a police statement, he stated: "When I got there, I saw [Owen's partner] and a girl in the street. We began to argue and I took a phone from the girl.

"All of a sudden, when we were arguing, I saw a man running at me and began to chase me in the street.

"He caught up with me and slashed my neck."

In court, Mr Karimi said he was struck on the face and neck before Owen fled.

He added: "At some point after he ran away, he said, 'I have to kill you' or 'I must kill you'."

Mr Karimi was left permanently scarred.

In his closing speech to jurors, prosecutor Christopher Fyfe said: "The injury to Mr Karimi's neck was potentially life threatening due to the proximity to an artery and nerves.

"Had he not received immediate medical treatment, his life could have been in danger due to blood loss and infection."

Sentence was deferred until later this month for background reports by judge Tom Hughes.

Owen, of Drumry Road East, Drumchapel, was remanded in custody until sentencing.
