David Savage stab attack: Callum Hackett denies murder
A teenager stabbed a man to death after earlier having sex with the victim's girlfriend at a party, a court has heard.
Callum Hackett, 18, denies murdering David Savage, 42, outside the older man's Newcastle home where the party was taking place in September 2015.
Newcastle Crown Court heard Mr Hackett, then 17, left the party, but returned with a knife and attacked Mr Savage.
Mr Hackett claims someone else carried out the fatal attack.
The court was told a friend of Mr Savage's girlfriend caught her in bed with Mr Hackett, who then left the party at Park Avenue, in the Gosforth area of Newcastle on 5 September 2015.
The prosecution claims that when he returned to collect his gloves, violence broke out and he came back a second time armed with a knife.
Mr Hackett, of Englefield Close, Kingston Park, Newcastle, earlier pleaded not guilty to fatally stabbing the father-of-two twice in the chest.
The trial continues.
