The Director of Criminal Investigations (DCI) George Kinoti has revealed that most bank fraud cases are inside jobs.
Kinoti has therefore warned banks and financial institutions to vet their own employees to avoid such cases.
Speaking on Friday, Mr Kinoti urged financial institutions to carry out effective background checks on their employees both potential and current.
Konoti's warning comes after Peter Sungu Nyakomitta, a branch Manager with Diamond Trust Bank in Kisii, was arrested over suspicion of stealing Sh25 million from customers’ fixed deposit accounts.
In a separate case, Abel Onyango, a relations officer with Family Bank, is accused of illegally withdrawing Sh1.5 million from customers’ accounts through SIM swaps.
The DCI on Sunday confirmed that the individuals had already been charged with fraud.
Elsewhere, Habil Onyango Owiti a manager at Harambee Sacco Limited, allegedly stole from the vault in smaller amounts cash amounting to Sh1, 783,392.
