Massive Attack frontman Rob Del Naja was taken into custody by police outside the Labour Party Conference in Liverpool. According to reports, the arrest was conducted under the UK's Terrorism Act 2000. Del Naja was reportedly holding a sign that stated, "I oppose genocide, I support Palestine Action" at the time of his detention.

The arrest follows the British government's decision on July 5, 2025, to officially proscribe Palestine Action as a terrorist group. Under current UK law, expressing support for a proscribed organization can be grounds for arrest under anti-terrorism legislation. Video footage circulating on social media shows Del Naja informing officers that he does not recognize the validity of the offense for which he is being detained.

While the arrest has drawn attention due to Del Naja’s public profile, the incident highlights the ongoing tension regarding the government's recent classification of Palestine Action. The organization has been involved in various direct-action protests, leading to the government's decision to categorize it as a terrorist entity. The advocacy group Defend Our Juries has commented on the situation via social media, though specific details regarding the legal proceedings following the arrest remain limited at this time.
