Have there been arrests of pro Palestine protesters not linked to Palestine action in UK?

1. How the proscription changed the legal landscape and why most arrests are linked to Palestine Action

When the UK government proscribed Palestine Action under terrorism laws this year, a new criminal offence was created of publicly supporting that organisation, and multiple news outlets document waves of arrests specifically for placards and slogans indicating support for Palestine Action — for example mass detentions at demonstrations organised to oppose the ban, including hundreds arrested in August and dozens in July and November, and sustained enforcement around signs reading “I oppose genocide, I support Palestine Action” ^{[2] [1] [3] [4]}.

2. Arrests at pro‑Palestine protests that were not explicitly about Palestine Action

Reporting also records arrests at pro‑Palestine demonstrations that were not framed solely as prosecutions under the proscription: police made arrests for allegedly shouting “intifada” and for other public‑order offences during large London marches, and separate incidents included arrests for alleged assaults or criminal damage during solidarity actions outside prisons or military sites ^{[5] [6]}. Those items show police action can be prompted by behaviour other than declarations of support for a proscribed organisation.

3. The conflicting narratives: policing, free expression and civil disobedience

Authorities defend arrests as lawful enforcement where people breach new terrorism‑support rules or commit public‑order offences, with police statements stressing they will act “where people are breaching the law by showing support for proscribed organisations” ^[1]. Civil‑liberties groups and organisers, by contrast, characterise many detentions as punitive suppression of peaceful protest and highlight thousands of arrests said to follow acts of non‑violent civil disobedience opposing the ban ^{[4] [2]}. Both narratives are present across the sources and reflect competing political and legal agendas: the government emphasises counter‑terror powers, while campaigners emphasise free speech and assembly.

4. High‑profile cases show the boundary‑test in practice but do not settle the broader question

High‑profile arrests — such as the detention and later release of prominent activists holding placards in support of Palestine Action — illustrate how the proscription has been applied in practice and fuel public debate, yet these cases are specifically tied to the organisation’s banned status rather than to general pro‑Palestine sentiment ^{[7] [8] [9] [10]}. The supplied reporting therefore demonstrates that many headline arrests are directly linked to Palestine Action’s proscription; they do not constitute clear evidence that people merely voicing non‑organisational support for Palestinians have been widely arrested under the same grounds.

5. What the supplied reporting does — and does not — show

Taken together, the sources establish that large numbers of arrests have occurred at protests concerning Palestine and that a significant portion of those detentions were for explicit support of Palestine Action or for actions organised in defiance of its ban ^{[2] [11] [4]}. The sources also record arrests for chants and alleged assaults at pro‑Palestine events ^{[5] [6]}. What the supplied reporting does not definitively document is a comprehensive catalogue of arrests of pro‑Palestine protesters wholly unconnected to Palestine Action or to other alleged criminal acts; therefore it is not possible from these sources alone to quantify how many arrests — if any beyond the Palestine Action‑linked cases — involved protesters whose conduct had no link to that group ^{[1] [12]}.

Conclusion: a qualified answer

Yes — arrests of pro‑Palestine protesters in the UK have occurred; most reporting supplied ties those arrests either to explicit support for the proscribed group Palestine Action or to alleged public‑order or criminal conduct at demonstrations, and the material here does not provide clear, documented examples of large numbers of arrests solely for general pro‑Palestine expression unconnected to Palestine Action ^{[2] [1] [5]}. The debate remains contested: police point to law enforcement needs while campaigners and rights groups point to suppression of dissent, and both perspectives are visible across the sources ^{[4] [1]}.
