A THUG brutally knifed a man who threatened his girlfriend.

Robert Young, 28, pounced on Damien Callaghan during an attack in Alexandria in May this year.

A judge heard Callaghan had previously left Young's partner shaken amid claims he was owed money.

Young later found the victim out walking his dog and repeatedly stabbed him.

The weapon was described in court as a “foot-long” kitchen knife.

Following the assault, witnesses heard Young stating: “I am going to jail. I have just stabbed f*** out of him.”

Prosecutor Greg Farrell told the High Court in Glasgow that Callaghan suffered five wounds.

He continued: “They were assessed as life threatening without treatment.”

Young was later arrested by police.

Mr Farrell added: “He eventually made admissions to stabbing Damien Callaghan.”

Young today (August 21) admitted assaulting Callaghan to his severe injury, permanent disfigurement and to the danger of his life.

Lord Clark remanded him in custody pending sentencing on October 7 in Edinburgh.

The judge said: “You have pleaded guilty to having a knife with you and then using it in a vicious and brutal assault.”
