Here is a focused list of organisations that are clearly and publicly identified as **filers of complaints / dossiers about crimes or war crimes in Gaza to the Metropolitan Police (SO15) or other UK authorities**, based on press and NGO statements.
I am limiting this list to cases where (a) Gaza is explicitly the context of the alleged crimes, and (b) the filer is clearly named in public reporting.
---
### 1. International Centre of Justice for Palestinians (ICJP)

Publicly reported Gaza-specific filings:

2. **Other HRF complaints tied to Gaza**

UK arms-trade campaign group.
Gaza-specific filing:
* **Sept 2025 – Complaint over DSEI exhibitors aiding Gaza war crimes**
* CAAT publicly announced that it had made a **criminal complaint** to the War Crimes Unit at the Met Police (SO15) concerning individuals exhibiting at the DSEI arms fair in London, for aiding and abetting Israeli war crimes in Gaza. ([CAAT][10])
Reference points:
CAAT press release and coverage (e.g. The New Arab) describing the complaint to SO15 over “aiding and abetting war crimes in Gaza.” ([CAAT][10])
---
### 8. Resistance Kitchen (campaign template re Elbit Systems UK)
Campaign group, primarily organising local activism.
Gaza-specific legal push:
* **Template letters urging SO15 war-crimes investigations into Elbit Systems UK**
* Resistance Kitchen has provided a campaign template urging residents to write to local police and the SO15 War Crimes Investigations Unit, calling for investigations into Elbit Systems UK for “suspected war crimes in Gaza”. ([resistancekitchen.uk][11])
This is, as published, a coordinated push for many individuals to file war-crimes reports related to Gaza. The template itself is a public, named effort to generate such complaints, although each individual complaint is filed by residents rather than by Resistance Kitchen as a single “dossier.”
Reference point:
Resistance Kitchen “Demand Criminal Investigation Into Elbit Systems UK” campaign page. ([resistancekitchen.uk][11])
---
### 9. “UK and international lawyers” teams (with Gaza focus)
In several cases, the press identifies the filers collectively as “UK and international lawyers” or “a team of legal experts”, but the underlying organisations are still the ones listed above.
Examples (Gaza-specific):
* The 240-page Gaza dossier on 10 Britons (PILC + PCHR; led by Michael Mansfield KC) described as being submitted by “UK and international lawyers” to the Met. ([The Guardian][12])
* ICJP’s complaints on Gaza war crimes and UK complicity, described variously as being submitted by “a UK advocacy group” or “NGO” in Al Jazeera and Anadolu Agency reporting, but clearly identified as ICJP. ([Anadolu Ajansı][13])
I have not added these as separate “groups” because the organisational identity is already captured under ICJP, PILC, PCHR, etc.
---
If you now want, the next refinement can be:
– narrow this list to only those who have filed directly to **SO15** (as opposed to more general “British authorities”); or
– add a column showing which specific incident(s) or time-period in Gaza each complaint covers (e.g. October 2023–, specific attacks, starvation policy, etc.).
