Overview
In this Payroll Diversion Fraud Investigation Case Study – Corporate Investigations UK, I led a sensitive enquiry into unauthorised payroll changes within a national company. With over 15 years of experience, I directed a structured investigation that delivered clear findings and secured Evidence to a Court Standard.
The Client’s Concern
The client identified unusual salary payment discrepancies affecting several employees. Initially, these appeared to be administrative errors; however, further review suggested deliberate interference. Therefore, the company instructed Corporate Investigations to establish the truth quickly and discreetly.
Investigation Strategy
Firstly, we conducted a forensic review of payroll records and access logs to identify anomalies. Next, we analysed system permissions and user activity, which revealed irregular access patterns. Additionally, we carried out background checks on staff with payroll system privileges.
Furthermore, we implemented targeted surveillance and digital tracing to monitor suspicious behaviour. As members of the Institute of Professional Investigators (IPI), we ensured every step complied with UK legislation and produced Evidence to a Court Standard.
Key Findings
During the investigation, we uncovered a payroll diversion scheme involving a member of the HR department. Specifically, the individual altered bank details of selected employees shortly before payment runs.
Consequently, wages were redirected into accounts linked to the suspect. Moreover, digital evidence confirmed repeated unauthorised access to payroll systems. In addition, behavioural patterns aligned with key transaction timings.
Therefore, we compiled a detailed evidential report, including system logs, financial tracing, and supporting intelligence suitable for legal proceedings.
Outcome
Following our findings, the client acted swiftly and suspended the employee involved. As a result, the matter was escalated to law enforcement with strong supporting evidence.
Importantly, the client recovered part of the diverted funds and strengthened internal payroll security measures. Additionally, stricter access controls were introduced to prevent future incidents.
