A Sudanese migrant has been arrested after a barbaric video shows someone seemingly trying to behead another man in the middle of a UK street in scenes likened to “something out of a horror movie.”

The horrific footage shows the blood-soaked knifeman pinning down his victim in Northern Ireland late Monday in an attack a local politician also branded “barbaric” and “medieval.”

The bloodied victim desperately kicked his legs before the knifeman repeatedly stabbed him in the head and neck, the video shared by Turning Point UK shows. 

“Get off him you f–king rat!” one woman shouted as the deranged attacker showed off his weapon — as a man yelled, “He’s trying to cut his head off. He’s slicing his head off.”

Horrified Belfast locals rushed over — and one clobbered the attacker with a stick as others tried to free his grip on the victim.

The victim, an unidentified local man in his 40s, was left with significant injuries to his eyes and serious slash wounds to his back and face, police said of the “brutal” attempted murder.

Northern Ireland police initially said the 30-year-old suspect was “believed to be Somalian,” before clarifying he was Sudanese, blaming the mix-up on the “fast time investigation” and without further identifying him. He was later charged with attempted murder, possession of a blade and threats to kill.

The suspect was living in the UK “under a five-year visa,” Gavin Robinson, the Democratic Unionist Party leader,  told the House of Commons — calling for him to be “convicted and deported on the first flight out.”

Police are still unsure of of a motive for the barbaric attack, but so far have “no information to suggest that this was a terrorist-related incident,” Ryan Henderson, the assistant chief constable of the Police Service of Northern Ireland, said in a press conference later Tuesday.

“However, I must stress, we are still at the early stages of our investigation,” he cautioned.

“This brutal attack has sent shockwaves through our communities, and I want to reassure all of our communities. Your safety is our priority.”

One resident told the Belfast Telegraph it was like “something out of a horror movie.”

“I’ve never seen anything like that in my life, it’s shocking,” another told the outlet.

One woman told the BBC she heard screams outside — and then saw children gathered in the street.

“I was just absolutely petrified,” one woman said, revealing she had “never seen anything like it.”

Local council member Paul McCusker told the BBC that at least one local woman was also hospitalized “because of the stress of witnessing such a brutal attack.”

British Prime Minister Keir Starmer condemned the attack, describing it as “sickening” and said he had “no tolerance for abhorrent scenes of violence like this on our streets.”

Democratic Unionist Party leader Gavin Robinson called it “barbaric” and “medieval.”

Henderson, the police chief, urged demonstrators to remain peaceful as calls for protests intensified.

“I want to stress that I absolutely understand that people will be feeling a range of emotions, from fear through to anger and more to have their voice heard… and if there are protests, we very much hope that they will be peaceful,” he said.

“And indeed, we would expect and hope that those people who may want to protest will allow people to go about their own lives.”

Locals will see an increased police presence in the area. “So my message is: please, if you’re feeling concerned or worried, please let us know,” Henderson said.
