Six people were arrested in Gosport on Tuesday evening after protesters “became hostile towards officers” when immigration officials abandoned plans to bring a Channel migrant boat ashore at the Hampshire harbour, police said.

Boat diverted after long crossing

The French coastguard said about 60 people spent more than 33 hours at sea in “precarious conditions” aboard a small dinghy and refused assistance, determined to reach the United Kingdom. British authorities eventually sent rescue craft to transfer the passengers, who were taken to Dover rather than Gosport after local opposition intensified.

Border Security Command said the group would be processed under standard arrival procedures. A government spokesperson said the command “works around the clock” to detain and check every small-boat crossing, but ministers faced fresh questions after a separate dinghy reached Folkestone on Monday without interception—the first undetected landing in a year. Home Office officials said they could not confirm how the Folkestone vessel evaded radar coverage while the Gosport diversion was under way.

Protests and arrests in Gosport

Hampshire and Isle of Wight Constabulary said hundreds of demonstrators gathered near Portsmouth Harbour amid reports the vessel might dock locally. When officials rerouted the landing, a smaller group remained in Gosport and confrontations escalated.

Police said six arrests were made for offences including careless driving, assaulting an emergency worker and aggravated trespass. Two Royal National Lifeboat Institution craft had escorted the migrant boat earlier in the day; the RNLI stressed its crews operate under maritime rescue rules independent of immigration policy.

Local political reaction

Conservative MP for Gosport Dame Caroline Dinenage said she had received confirmation that Border Force intercepted the boat and was transporting occupants to Dover by water. Gosport Borough Council leader Zoe Huggins joined Dinenage and the police and crime commissioner in arguing that Portsmouth Harbour is “not suitable” for small-boat arrivals, citing narrow channels and limited processing facilities.

Defence minister Luke Pollard, asked about border security on Tuesday, said a Home Office review was under way into Monday’s Folkestone landing and declined to discuss operational details. Labour’s front bench has promised new agreements with France on joint patrols, but Tuesday’s events showed how quickly local protests can reshape where migrants step ashore.

What happens next

Those arrested in Gosport were released under investigation pending charging decisions. Immigration officials must now house and interview the Dover arrivals while prosecutors assess whether any organisers facilitated the crossing.

For Gosport residents, the evening ended without a landing—but not without injury risk to officers and renewed debate over whether Channel policy can be enforced without turning harbours into flashpoints. Refugee charities urged ministers to avoid announcing provisional dockings before secure processing sites are ready, arguing that leaked itineraries had drawn crowds to Gosport before police could stage adequate cordons.
