A monitoring group repeatedly warned the Police Service of Northern Ireland (PSNI) over the past eight months that anti-immigration activists were circulating the addresses of properties that were targeted in this week’s Belfast riots.The Accountability Project Northern Ireland, a volunteer group formed last summer to monitor anti-immigration activity online, sent dozens of reports to police between November 2025 and June 2026.They warned of a growing focus on houses of multiple occupation (HMOs) by anti-immigration and far-right actors, something they first observed in August 2025.The Guardian understands a so-called hitlist of addresses has been circulating among far-right groups since August 2025 and was sent to the PSNI in January 2026. They were among the locations targeted during this week’s anti-immigration disorder.

The Guardian has seen a screenshot of an email sent to a PSNI inspector in January attaching one such list. Campaigners say a similar list is now being circulated on social media and messaging apps amid this week’s rioting. The PSNI warned earlier this week against the sharing of home addresses, adding it has left families and residents “extremely distressed”.The reports sent to the PSNI focused heavily on activity in the Newtownabbey area north of Belfast, which has been at the centre of some of the most serious disorder in recent days. Speaking on BBC Radio 4’s Today programme, John Blair, an Alliance assembly member for South Antrim, said the area had seen “a mob on a rampage of violence and destruction”.The reports sent to police also cited a Facebook post stating that HMOs in the Glengormley area “will now be treated as fair game and dealt with accordingly”. It went on to state: “Anyone caught funding or helping these animals in being housed will be condemned as equally guilty.”
