A revenge fuelled knifeman slashed his ex's Tinder date to the face in a horrifying attack after finding them in bed together. Derek Malcolm let himself into her home before brutally attacking a man she'd been on a date with that evening.
The pair were both asleep in bed when Malcolm started punching him. Drink and drug fuelled Malcolm, 34, who his victim described as being 'off his t*ts', then went downstairs and armed himself with a knife.
Malcolm went back to the bedroom and slashed him to the face, leaving him requiring 14 stitches and sustaining permanent scarring. He believed he was going to die as raging Malcolm unleashed his jealous fury.

"She had moved on with her life and begun dating other men," sentencing Judge Hilary Manley said. "You could not accept that and you would not stand for it."
Now Malcolm has been declared 'dangerous' and handed an extended sentence for public protection. Manchester Crown Court heard that Malcolm and his ex had been in a relationship for eight years, but split in 2019.
The year before they broke up, Malcolm was hauled before the courts for attacking her during a row. Using the dating app Tinder, she met the man and agreed to go on a date.
They went for drinks in Bury town centre and later returned to her home and slept in the same bed. In the early hours of August 7 last year, the man, who has previously served in the army, was woken to find he was being punched repeatedly.
Malcolm stopped and left the room, but he returned seconds later armed with an 18cm kitchen knife. She pleaded with him to stop but Malcolm shoved her out of the way and she collided into a piano.
During the attack Malcolm slashed the man to the face, inflicting a 'large wound'. Malcolm only stopped as his ex jumped him, and he left the house shortly after.
The police were called after 1am, and seized the knife. Hours later Malcolm then began to abuse her for calling the police, calling her a 'rat', a 'grass' and as 'vermin', prosecutor Alaric Bassano said.
He 'threatened' her and ordered her and the man he attacked not to co-operate with police. But after a trial Malcolm was found guilty of wounding with intent, assault and perverting the course of justice.
"You have no real remorse, and you have no insight into your distorted thinking and jealous and controlling attitudes," the judge told him. In a statement, Malcolm's victim said: "I was in the armed forces for nine years and I have never been scared of anything, but this happening to me has had a really bad effect on me.
"I have seen some horrendous things throughout my life and certainly my time in the army, including the loss of friends and those friends losing their lives in front of me. I have never been scared, and things have never affected me in the way that this has.
"This has scared me more than anything I have ever experienced in my life." A psychiatrist has said he probably has post traumatic stress disorder.
Defending, Adam Roxborough said there is a 'different side' to Malcolm, who he said was a 'successful footballer' in his youth before he 'fell in with the wrong crowd'. But Judge Manley told Malcolm: "Many people have personal difficulties and setbacks in their lives.
"There is nothing in your past that can possibly begin to explain and justify how you have turned out in terms of your violent and controlling behaviour." Malcolm, of Langley Grove, Prestwich, was sentenced to an extended sentence, comprising of 13 years in prison and an additional five years on licence.
