The Arrest of Zack Griffiths: A Movement Tested, A System Exposed
©️ By Sophie Lewis | HMP Prisons Justice Group / The Indie Leaks |@realtalkrealtea

On the morning of 10 April 2025, HMP Prisons Justice Group co-founder Zack Griffiths was arrested live on video outside his home. The officer is clearly heard stating that Zack was being arrested under Section 43 — a charge which, on review, does not correspond to the UK’s blackmail legislation, which is actually defined under Section 21 of the Theft Act 1968.
This discrepancy raises immediate concerns about due process, clarity of the charge, and whether the arrest was carried out with accurate legal grounding. At the time of writing, Zack remains in custody. Legal representation has been contacted, but his location has not yet been confirmed.
A Voice for the Voiceless — Silenced

Zack Griffiths has become a leading voice in the grassroots movement demanding accountability for unexplained deaths, inhumane conditions, and systemic failures inside HMP Parc, a privately run prison operated by G4S. Alongside the Predator Awareness team, he has helped drive forward investigations, organise peaceful demonstrations, and give voice to families failed by silence.
Zack is no stranger to state pressure. His past includes time inside the very system he now challenges. It is that lived experience — and his refusal to stay silent — that made him a threat to the status quo.
This arrest is not a coincidence. It is a direct response to resistance.
Live, Public, and Strategic
The fact that Zack’s arrest was caught on camera, live-streamed to supporters and the public, is crucial. It makes this moment impossible to quietly bury or distort. The video reveals an officer citing “Section 43,” which, upon legal review, appears to not match the crime referenced — commonly understood to be blackmail. The correct legal reference for blackmail is Section 21 of the Theft Act 1968.
Whether this was a misstatement or a procedural issue remains unclear. What is clear is that Zack was removed from public space in real time, in front of the very community he’s been fighting for.
The Movement Responds

In the hours following the arrest, the HMP Prisons Justice Group and its supporters quickly mobilised. Public statements were made. Legal calls were placed. Internal team structures were reinforced. The mission hasn’t changed — if anything, it’s been made clearer.
The group released the following statement:
“This development, while unexpected, does not change the heart or mission of our campaign. We remain committed to standing with families, exposing systemic failures, and demanding justice for those harmed behind the walls of HMP Parc and beyond. Our campaign was never built around one person — it was built around truth, accountability, and resistance. That work continues.”
What Happens Next?
Supporters are now calling for full legal clarity, proper representation, and a public review of Zack’s arrest. Many are raising the alarm about what they see as a tactical takedown — not based on evidence, but on Zack’s influence and visibility.
The campaign is asking its supporters to:
- Remain calm but vocal
- Continue amplifying the campaign’s message
- Refuse to be distracted or divided
- Demand due process and transparency in all legal proceedings
Final Word

This isn’t just about Zack. It’s about what happens when someone speaks too loudly, too honestly, and refuses to back down.
If the system hoped to shake the movement — it miscalculated. Because the response hasn’t been fear. It’s been fire.
Zack Griffiths stood up for the voiceless. Now the movement stands for him.
We will not be silenced. We will not be swayed. We will not stop.
