Police investigate Portsmouth anti-migrant protest after officers injured

Police were investigating suspected assaults and criminal damage on September 7 after an anti-migrant protest in Portsmouth left officers injured and official vehicles damaged, Sky News reported. The confrontation followed the arrival of migrants by sea on Sunday and delayed their onward transport, bringing a border reception operation into an overnight public-order dispute.

Sky's reporting from the scene described objects being thrown at police. The force said a small number of officers received treatment there, while nobody from the agencies or public suffered serious injuries. Vehicles belonging to police, the Coastguard and Border Force were damaged. These reported injuries and damage are the basis of an investigation, rather than findings of guilt against identified individuals.

Ministers set out the overnight sequence

In a statement to Parliament on Monday, policing minister Sarah Jones said the boat had reached British waters near the Isle of Wight, further west than most crossings. The RNLI, operating under Coastguard direction, guided it towards Eastney Marina. She said more than 200 protesters subsequently arrived intending to block three coaches taking the arrivals for processing.

Jones said police used a dispersal notice, batons and PAVA spray during the response. Protesters began dispersing around 4am, allowing the coaches to leave. No arrests were made that night, she told MPs, but investigations continued. The government was also reviewing operational lessons and intelligence sharing. Its account separated protection of peaceful protest from action against threatening behaviour and serious disruption.

The cross-Channel policy context

The incident comes within an established programme of British-French cooperation. An agreement announced on April 23 provided for stronger patrols, intelligence capabilities and surveillance in northern France. Its published terms included a flexible funding component, regular joint evaluation and the possibility of redirecting money if measures did not sufficiently prevent crossings. That earlier agreement supplies policy context, rather than evidence about Sunday's individual passengers.

The immediate questions are whether investigators identify offences and what changes follow the operational review. The wider issue is how authorities coordinate maritime rescue, reception and safe transport when arrivals occur away from the most familiar routes. Evaluating that response requires keeping the criminal investigation distinct from the separate assessment of cross-Channel enforcement. Neither the protest nor a single landing establishes whether the bilateral programme is succeeding overall.
