The inquiry is expected to examine whether established procedures were followed and if any irregularities may have allowed substandard fuel to enter the system.
Investigators are also seeking to establish how the fuel in question made its way into the country and whether there were lapses at critical points in the importation and distribution chain.
Particular attention is being placed on compliance with quality assurance standards and the roles played by various agencies tasked with oversight.
The development follows the arrest of four senior government officials over allegations of procuring substandard fuel, a situation that has raised fresh concerns about fuel quality across the country.
The arrests have drawn significant public attention, given the potential impact of such claims on consumers and the broader economy.
Authorities are expected to scrutinise documentation related to procurement approvals, inspection reports and testing procedures to determine whether due process was adhered to.
The probe may also look into whether there was any deliberate attempt to bypass regulations designed to safeguard the integrity of petroleum products.
The case has intensified scrutiny on institutions responsible for regulating and managing the energy sector, with stakeholders calling for transparency and accountability.
Concerns have been raised about the effectiveness of existing oversight mechanisms and whether they are robust enough to prevent similar incidents.
While investigators continue to gather evidence, no formal charges have been announced, and the officials remain in custody pending further action.
Legal experts note that the outcome of the investigations will depend on the strength of the evidence collected and whether it meets the threshold for prosecution.
The situation has also sparked wider debate about the need for reforms within the fuel supply chain to enhance accountability and ensure compliance with standards.
Industry players and consumers alike are calling for stronger safeguards to protect the market from compromised products.
