On Tuesday 18/12/07, activists from the No Borders Network, marked UN International Migrant's Day, by blockading immigration reporting centres in Glasgow, Bristol, Newcastle and Portsmouth. Arriving at the centres in the early hours of the morning, the activists aimed to prevent Immigration Enforcement Officers from staging dawn raids, in which families are often rounded up in preparation for removal to countries from which they have been forced to flee.

In Bristol, activists arrived in time to lock onto vehicles, and a police officer wasoverheard confirming that a dawn raid had been planned. In Portsmouth, activists were locked onto the swing barrier and gates by 4.30am and believe that another dawn raid from that site was thwarted. Glasgow activists were in place by 5.30am when Immigration Enforcement Officers arrived and were unable to leave the car park with their vehicles due to a tripod, and people d-locked to the gates. Newcastle activists dressed in Santa outfits locked onto the gates and used arm tubes to prevent vehicles from leaving the car parks. 2 of the Glasgow activists were cut free from their D-locks and arrested, whilst a tripod continued to ensure that vehicles could not leave the car park. Activists at the other sites were able to leave without any arrests taking place.

In Manchester, the local Immigration Reporting Centre Dallas Court had its gates locked with a motorcycle chain, and a banner reading "Caution snatch squads – we are watching you” was hung. Later, at 10 am, the Home Office in Marsham Street SW1, London was disrupted after activists blocked the entrance and unfurled a large banner declaring "No Child is Illegal: Child Detention is a Crime".
