After footage of a stabbing attack in Belfast was widely circulated on social media, questions have been raised about how the suspect, Hadi Alodid, came to the UK, what his immigration status was and whether he was known to the authorities.

One claim made in the aftermath of the attack was that his presence in Belfast was evidence of a dangerous “back door to Britain” via a route that should be closed.
