When fraud has been detected following an incident, a forensics audit is the most relevant type of audit to conduct. A forensics audit is specifically designed to investigate and uncover evidence of fraud, misconduct, or other financial crimes. It involves the use of auditing and investigative skills to examine financial records, identify irregularities, and gather evidence that can be used in legal proceedings1.

References: The information aligns with the guidance provided by ISACA, which suggests that when fraud is suspected or detected, an audit should focus on the forensic examination of the evidence to understand the nature of the fraud and to gather proof1. Additionally, the role of internal audit in such cases is to assess the controls in place to prevent fraud and not necessarily to investigate the fraud itself unless they have the specific experience and expertise required1.
