Police in Northern Ireland arrest a man on suspicion of attempted murder following a knife attack in north Belfast that draws national attention after graphic footage is shared online. Officers said the incident happened on Kinnaird Avenue shortly after 10.30pm on Monday. The victim, reported as a man in his 40s, is taken to hospital with serious injuries, including wounds to his face, neck and back.

Police say the suspect is a Sudanese man in his 30s and is in custody. Authorities describe the attack as a critical incident and say a major investigation is ongoing. The circulation of videos on social media leads to public shock and prompts calls online for wider protest.

In response, UK Prime Minister Keir Starmer’s office calls for calm while police continue their work. Coverage of the incident includes descriptions of the attack videos and reactions from political and public figures, though all reporting centers on the same arrest, location, timing and the victim’s serious condition.
