A video has emerged of a convicted killer making terrifying threats to kill another man during a blazing pub row.

Murderer Christian Williams has since be convicted of the merciless killing of Andrew Hamilton, who he brutally stabbed and clubbed in an unrelated incident last July.

The 44-year-old claimed he had acted in self-defence, but newly released footage shows him to have an explosive temper.

In the video, filmed two years ago in a pub in Liverpool where Williams was studying as a mature student, he yells threats at a fellow student as others try to hold him back.

Williams can be heard creaming ‘I’ll kill you, I’ll eat you’ before tackling the man onto the ground, North Wales Live reports.

The victim later shows what he claims as a bite mark from where Williams, who was studying as a mature student at the time, had sunk his teeth into his forearm.

Another student, who asked not to be named, remembered Williams as having a fierce temper.

“There was something about him even then," the student said. "He stood up and had a go at us in lectures once. He just kicked off because we were talking. It was well out of proportion and he made a massive scene,” he said.

A witness to the incident said Williams, 41 at the time, was explaining how people 'took the p***' out of him and he was proclaiming how he wasn't scared of, and would take on, anyone.

"The initial thing was he punched the table and glasses were smashed and he caused about £200-300 worth of damage in the bar.

"He also bit someone. He acted in a very over-exaggerated manner. I think he panicked. It was almost like he was blacked out."

Police attended the scene but Williams had left by the time they arrived.

The footage has emerged as Williams, of North Wales, was convicted on Thursday of the murder of Andrew Hamilton, who he brutally stabbed to death last July.

Williams claimed he did not intend to kill the 42-year-old Mr Hamilton at his flat in Bagillt, North Wales on July 18, 2018.

The victim had his throat slit and left to bleed to death.

The eight-day trial heard Williams used a saucepan, a bottle and a kitchen knife during the attack - leaving Mr Hamilton with 95 injuries including 25 to the head and body.

Judge Rhys Rowlands told Williams that Mr Hamilton had sustained the "most horrible of extensive injuries".

The court heard Williams denied any weapons had been used and Mr Hamilton had attacked him "like a lunatic".

He claimed to police there had been "a tussle" and he had merely defended himself.

Williams will be sentenced on Monday.
