Barclays bank has now suspended the safe deposit boxes service.
The suspension comes after sleuths from the Directorate of Criminal Investigations (DCI) impounded Sh2 billion fake currency at the bank's branch in Nairobi.
Detectives have embarked on a probe to determine the circumstances behind the fake currency following the arrest of Eric Adede, who is believed to be the owner of the safe where the fake currency was stored.
Adede was arrested alongside Ahmed Shah, Elizabeth Muthoni and Irene Wairimu Kimani.
The suspects were arraigned in court on Thursday.
The court denied them bail and ordered for their detention for five more days pending probe. The bank has decided to suspend the service as investigations continue.
In a statement released to media houses, Jeremy Awori, Barclays Bank Chief Executive Officer said that the financial institution will not offer the service until further notice.
He also said that the bank is working with the clients to ensure a new system is adopted as it seeks to prevent similar sagas in the future.
"As an extra precaution, we have taken a decision not to take any new safe deposit boxes and are working with our clients to review the existing safe deposit boxes," read the statement, as quoted by Standard.
