Case Studies
First Equity Enterprises - BOILER ROOM FRAUD
This fraud investigation involved the representation of 322 clients from 30 countries in respect of the loss of USD $100 million. The funds were lost as a result of a Russian organised crime fraud operation based in New York. Warden froze funds in a BNP Paribas account in Geneva through a private Seizure Order. It was subsequently established this account contained $4.7 million and that the following day one of the offenders in the boiler room (Gary Faberov) attempted to shift these funds from the account. In the absence of the Seizure Order, Mr Faberov would have been successful. In total Warden recovered over $10 million.

Warden Consulting Fraud Investigation Process
Our investigators plan, adapt and execute:
Assemble victim group(s)
Depending on the size and nature of the fraud it may be preferable to form a victim group in order to combine resources and share information about the offender(s).
Gather Information
The key step in any financial investigation is to collect evidence. We start by receiving and analysing initial information, including financial records, documents, and witness statements. We also conduct extensive background checks on targets. Information is gathered from company registers, bank accounts, credit cards, property titles, surveillance and digital profiles. This helps us establish a solid foundation for our investigation and identify potential red flags.
In-Depth Analysis
Leveraging our law enforcement experience and expertise, we conduct thorough analyses of financial transactions and data to find targets, uncover irregularities, patterns, and discrepancies.
Trace offenders
We use a variety of tracing methods, utilising traditional, digital and covert methods. By following the money we begin to paint a picture of the fraudsters' operation.
Collaboration with Experts
The case can be strengthened by pooling our resources with experts. We collaborate with forensic accountants, legal experts, cybersecurity professionals, and other specialists to enhance our investigation.
Conduct interviews
At this point we may conduct interviews with the offenders. Our law enforcement and legal background allows us to pressure the offenders, who may return the funds to our clients in order to avoid jail time or further investigation.
Reporting and Legal Action
Our team compiles detailed reports presenting our findings, analysis, and recommendations. These reports serve as crucial evidence in legal proceedings, supporting law enforcement agencies and legal professionals in taking appropriate action against fraudsters.
Freezing Bank Accounts and Seizing Assets
We obtain court orders based on the evidence gathered throughout the case. The next step is to liaise with financial institutions to trigger the freeze of specified accounts. We also coordinate with law enforcement to seize physical assets such as property or vehicles. We may oversee civil litigation and push to ensure that the proceeds of all assets will be distributed to our clients.
Distribution of Assets
If the case enters the legal system our main main focus is to secure a court issued judgement that will direct funds back to clients. We push to create a distribution plan that outlines how the recovered funds will be allocated among our clients. The plan includes factors such as proportioning the share of each client's claim and other legal considerations. We then disburse payments through our forensic accountant for security and transparency.
