The video, filmed from an upstairs window on Kinnaird Avenue, appears to show a man pinned to the ground while another man repeatedly strikes at his head and neck with a blade. Witnesses can be heard screaming in distress as the attacker leans over the victim in what looks like an attempt to behead him.

Police and emergency services were called to the scene following reports of a serious assault. Officers arrived to find a man suffering from multiple stab wounds. He was taken to hospital for treatment; his condition has been described by authorities as serious but not believed to be life-threatening.

The suspect, described by some online commentators as a Somali national, was detained by police shortly after the incident. Law enforcement has not formally confirmed his nationality, stressing that the investigation is at an early stage and that speculation on social media should be treated with caution.

Detectives from the Police Service of Northern Ireland have appealed for witnesses and anyone with additional footage to come forward. They are examining the widely shared clip as part of their inquiries and have urged the public not to repost graphic material out of respect for the victim and his family.

Local residents say the attack has left the community deeply shaken. Kinnaird Avenue, a typically quiet residential street, was sealed off for several hours as forensic officers examined the scene, photographing bloodstains on the pavement and collecting potential evidence.

Community representatives have condemned the violence and called for calm, warning against attempts to use the incident to inflame racial or political tensions. They have urged people to allow the criminal justice process to run its course and to avoid drawing conclusions based solely on online commentary.

Police have confirmed that a man has been arrested on suspicion of attempted murder and remains in custody. Officers are working to establish the circumstances leading up to the attack, including any prior connection between the suspect and the victim, and whether the assault was premeditated.

Authorities have encouraged anyone affected by the disturbing footage or the events on Kinnaird Avenue to seek support, as the community grapples with the aftermath of an attack described by witnesses as one of the most shocking acts of street violence they have ever seen.
