GSA Global provides investigation and evidence-development support for matters being assessed or pursued as private prosecutions, working alongside and under the direction of solicitors and counsel.

Legal advisers may require additional investigation to establish facts, identify witnesses, fill evidential gaps, develop chronologies or undertake corporate and open-source enquiries. Equally, an organisation that believes serious wrongdoing has occurred may need the underlying evidence organised and developed before its legal advisers can properly assess whether a private prosecution is an appropriate route.

GSA provides the investigative component of that process, gathering, assessing and documenting evidence in coordination with the legal team. We do not act as prosecutor, provide legal advice or determine whether proceedings should be commenced; our role is to give solicitors and counsel a clearer and properly documented evidential picture on which to advise their client.

Working Alongside Solicitors and Counsel

The division of roles is clear. The solicitors and counsel advise on the law, assess evidential sufficiency, make the decisions about commencing and conducting proceedings, and own disclosure strategy. GSA conducts the enquiries the legal team directs, reports findings — helpful and unhelpful alike — and maintains the investigative records the legal team’s obligations depend on. Unhelpful material is recorded and reported with the same care as supportive material.

OSINT and Corporate Intelligence

Ellen Davies, our Lead Open-Source Investigator, supports prosecution casework with corporate intelligence on defendants and connected entities, identification of assets and interests from lawful public sources, network analysis and evidentially captured open-source material. Asset-related findings can inform the legal team’s parallel civil-recovery or restraint strategy; we identify what lawful sources reveal, and we do not guarantee that assets will be found or recovered.

Witness Enquiries

Witness evidence in a prosecution context requires particular care: accounts can be affected by leading questions, by exposure to other accounts, or by any suggestion of inducement. Witness enquiries are coordinated with the legal team, planned to avoid those risks, and documented: who was approached, when, by whom and what was said. Where the legal team prefers to take statements itself, we can locate witnesses, make initial contact and hand over cleanly.

Investigation Records and Deliverables

Because the investigation itself may be examined in contested proceedings, the record of the investigation is a deliverable in its own right. Legal teams receive: the agreed terms of engagement; the investigation plan and its revisions; enquiry logs recording investigative actions and results; records of witness interactions; chronologies; evidence schedules identifying each item and its source; investigation reports written for the legal team’s use; and stated limitations. Disclosure decisions are for the legal team; our job is a record complete enough to support them.

Our Private Prosecution Investigation Team

David Wood provides senior oversight, drawing on 31 years of Metropolitan Police service including command of organised-crime and anti-corruption investigations and six years helping build Northern Ireland’s independent police-accountability investigations. Bob Quick QPM provides senior direction on matters involving corruption, serious wrongdoing or prominent parties. Ellen Davies leads the open-source and corporate-intelligence elements. Where the evidence includes compromised accounts or systems, GSA can draw on its cyber-security capability, with Mark Raeburn providing strategic direction, Anthony Dickinson overseeing the technical work, and appropriately appointed digital-forensic specialists coordinated where formal forensic acquisition is required for evidential purposes.

Our Private Prosecution Investigation Support Capabilities

Investigation Support for Private Prosecutions

A private prosecution may be considered in circumstances where an organisation or individual and their legal advisers decide that privately initiated criminal proceedings should be assessed most often following fraud, theft or other wrongdoing that has caused serious harm. The practical question is capability: who will conduct the enquiries, organise the evidence and document the investigation to the standard the proceedings will require. That is the role we fill, typically instructed by and reporting to the prosecuting solicitors from the earliest stage, so that the investigation is shaped by the legal team’s assessment of the case.

Case Assessment and Investigation Planning

At the outset we work with the legal team to map the evidential position: what evidence exists and in what condition; what the lawyers identify as required by way of proof; where the gaps are; and which enquiries could realistically fill them. From that, an investigation plan is agreed, with the legal team directing priorities. Assessment of legal viability and the decision to prosecute are matters for the solicitors and counsel; our contribution is an honest investigative appraisal of what can and cannot be evidenced.

Evidence Gathering and Case Development

Under the legal team’s direction, we gather and develop the evidence the case requires: identification, collection and organisation of documents and records, with provenance documented; witness identification and, where instructed, witness enquiries; construction of chronologies from the assembled evidence; corporate and registry research into the entities and individuals involved; and open-source investigation applying the disciplines described on our OSINT and digital footprint investigation services page. Where the underlying conduct is fraud, the most common foundation of the prosecutions we support, the approach described on our corporate fraud investigation services page applies, with the additional care in record-keeping that criminal proceedings demand. Throughout, material is handled and recorded on the basis that it may be exhibited, disclosed and challenged.

Asset Tracing and Financial Recovery Support

Where appropriate, GSA supports private prosecutions with asset tracing and financial investigations, helping identify proceeds of crime and support recovery strategies. This is particularly relevant in fraud, theft, and financial crime cases where restitution and deterrence are key objectives.

Sensitive, High-Risk and Safeguarding Cases

GSA has extensive experience managing sensitive and high-risk private prosecutions, including those involving safeguarding concerns, vulnerable individuals, reputational exposure, or complex organisational dynamics. We apply a trauma-informed, proportionate approach, balancing legal robustness with duty of care and reputational protection.

Frequently Asked Questions (FAQs)

What is a private prosecution?

A criminal prosecution brought by a private individual or organisation rather than a public prosecuting authority,  a route recognised in England and Wales, conducted through solicitors and counsel. Whether it is available and appropriate in your case is a question for a solicitor.

What is GSA Global’s role?

The investigation: gathering, developing and documenting the evidence under the direction of the prosecuting legal team. We do not prosecute, advise on law or decide whether proceedings should be brought.

Do I need a solicitor?

Yes. A private prosecution is a legal proceeding requiring advice and conduct by qualified lawyers. Our consistent advice is to instruct a solicitor experienced in private prosecutions early; we work best when instructed alongside or through them.

What types of evidence can GSA help gather?

Documents and records with documented provenance, witness accounts, chronologies, corporate and registry research, open-source material captured evidentially, and coordinated technical evidence — assembled into schedules and reports for the legal team.

Can GSA interview witnesses?

Where instructed by the legal team, witness enquiries are planned with them, conducted without leading or influence, and fully documented. Where the legal team prefers to take statements directly, we support with witness identification and initial contact.

Does GSA decide whether a prosecution should proceed?

No. That decision belongs to the client, advised by solicitors and counsel. We provide the evidential picture on which that decision is made including its weaknesses.
