Was the person injured in what news media described as an attempted beheading in Belfast as young as 15 years old? No, that's not true: The authorities said the victim was a man in his 40s. He was in the hospital in serious condition but alive as of June 9, 2026.
The claim appeared in a post (archived here and here) on X published by @Anc_Aesthetics on June 9, 2026. It opened:
I'm hearing that the White kid who was beheaded in Belfast was only 15 years old...
This is what the post looked like on X at the time of writing:

Contrary to the claim on social media, the police press release (archived here and here) described the victim as an adult:
The injured man, aged in his 40s, is in hospital where his condition is described as serious. The attack has left the man with significant injuries to his face, neck and back.
The Belfast Telegraph (archived here and here) added that the man had "significant injuries to his eyes".
Other news reports -- for example, here (archived here), here (archived here) and here (archived here) -- also described the victim as a man in his 40s.
A viral video said to have captured the attack did not show the injured person clearly enough to state anything definitive about their age.
The attack took place in the capital of Northern Ireland, U.K., on June 8, 2026, between 10 and 11 p.m. local time. The suspect was taken into custody.
No credible media outlet, at the time of writing, reported that the victim had died.
