The Lagos Banking Fraud Investigation
Case Summary
A major Nigerian bank discovered a series of suspicious transactions totaling over ₦500 million across multiple branches. The transactions were authorized with signatures that appeared to match those of account holders, but the account holders denied making the transactions.
IFGN was engaged to examine over 200 questioned documents to determine the authenticity of the signatures and identify potential forgeries.
Our Approach
- Comprehensive examination of all questioned signatures using VSC technology
- Comparison with known genuine signatures from bank records
- Analysis of writing pressure, line quality, and formation characteristics
- Digital enhancement and microscopic examination of suspicious elements
Outcome
Our examination revealed that 85% of the questioned signatures were sophisticated forgeries created by a small group of individuals. We identified unique characteristics that linked the forgeries to three bank employees working across different branches.
The evidence was presented in court, leading to the conviction of the perpetrators and the recovery of ₦420 million in stolen funds.
