The branch manager knew her name. The pounds left anyway.
A Nairobi branch manager, her deputy, and a junior colleague stand accused of bleeding a customer's pound-sterling account at Diamond Trust Bank for almost a decade. The fraud, prosecutors allege, was not a hack. It was the bank doing what the bank does, with the signatures faked from the inside.
The branch was on Forest Road. Parklands, Nairobi. The kind of branch where the manager knows your name because your family has banked there for thirty years, where the deposit slip is half-filled before you reach the counter, where the woman behind the desk asks how your children are doing in London.
Rozina Nurdin Patelia kept a pound-sterling account at that branch. A foreign-currency account. The kind of account a person opens when they have family abroad, or property abroad, or a daughter studying somewhere the fees are billed in GBP. It was not the account she lived from. It was the account she kept quiet.
That is the kind of account that gets stolen from slowly.
According to charges filed at the Milimani Law Courts on June 2, 2026, three former DTB employees emptied Patelia's accounts of Sh149,235,387, roughly $1.15M USD, over five years. The lead defendant is Salimah Ameen Pirbhai, age 55, former Parklands Branch Manager. The second is Aabid Alkarim Kassam, 43, former Assistant Branch Manager. The third is Tazim Sidi Vassanji, 57, described in the charge sheet as their accomplice.
All three pleaded not guilty.
Read the charge sheet slowly. The thefts were not one event. They were a calendar.
Between October 31, 2016, and April 5, 2018, Kassam alone is alleged to have taken Sh58,244,167 from Patelia's account. Between June 14, 2019, and October 4, 2021, another Sh10,914,400 from the same account, also attributed to Kassam. Between July 5, 2019, and June 26, 2020, the trio together is accused of pulling GBP 233,270.17 out, about Sh40.6M (around $295K USD at the time). And separately, on a single day in June 2025, Pirbhai is alleged to have taken Sh39,587,840 from DTB itself.
Sixty-eight counts in total. Conspiracy to steal. Stealing by servant. Money laundering. Making false documents. Uttering false documents.
"Uttering false documents" is the legal term for handing a forged paper to someone who treats it as real. In this case the someone being handed the forged paper was the bank. The bank was handing it to itself.
II. The mechanism
This is the part that should make you put down your coffee.
The prosecution alleges the money left through fabricated instruction letters, fictitious withdrawal slips, and fraudulent emails. Not a hacked password. Not a stolen card. Paper. Paper produced inside the branch, signed by people inside the branch, processed by people inside the branch, approved by the manager of the branch.
A bank account, when you strip away the app and the SMS alerts and the marble counters, is a permission system. You give the bank money. The bank promises only to release it back when you say so. The signature on the withdrawal slip is the lock. The teller is the checker. The branch manager is the override.
If the branch manager is the one forging the slip, the lock is the thief.
That is what the charge sheet alleges happened at Parklands. For nine years.
III. The customer who did not know
Picture Rozina at her kitchen table. The statement arrives. It arrives quarterly, the way GBP statements often do for accounts that are not used much. She glances at it. The balance looks roughly right, or roughly close to what she remembers. She is not a banker. She does not reconcile. Nobody reconciles a sleepy account.
If anyone questions a missing figure, the branch manager can be called. The branch manager will know. The branch manager has known her for years.
This is the soft tissue of private banking. It is also the soft tissue of insider fraud.
According to the charges, the first alleged withdrawal happened in October 2016. The investigation did not begin until July 2025. That is nine years between the first cut and the first question. Nine years of statements. Nine years of quarterly glances. Nine years of a woman trusting a building.
IV. What the bank says, and what the record says
Diamond Trust Bank has not issued a specific public statement on these charges as of this writing. In previous cases, the bank has said it cooperates with investigators and takes financial crime seriously. That language is standard. It is also what every bank says.
The record is less standard.
In 2018, the Central Bank of Kenya fined DTB Sh80 million for failing to report large cash transactions and conduct proper customer due diligence in matters connected to the National Youth Service scandal. In 2019, a DTB branch manager was charged with failing to report suspicious transactions linked to a terrorist attack. In January 2026, a former DTB employee named Amos Kahuro Njuguna was charged with stealing Sh1.1M from the bank between September and December 2025.
Now this. June 2026. Sh149M. Parklands. Three insiders.
One case is misconduct. Two is a problem. Four, across eight years, is a question about whether the controls inside the building work the way the building's marketing says they do.
That is not a verdict. It is arithmetic.
V. The courtroom
On June 2, 2026, the three defendants appeared before Senior Resident Magistrate Irene Thamara at Milimani. They denied all 68 counts. Pirbhai and Vassanji were granted bond of Sh1M each with cash bail alternative of Sh300,000. Kassam, charged with the largest individual sums, was granted bond of Sh2M with cash bail alternative of Sh500,000.
The case returns to court on June 17, 2026.
Patelia, the named complainant, was not in the dock. She was the line item the charge sheet was built around. Her GBP account, the one she kept quiet, the one she trusted the manager to watch. The one the manager is alleged to have watched too closely.
VI. What this is
This is not a story about a bank getting hacked. This is a story about what a bank is when the people you hand the money to are the ones taking it.
The lock was the manager. The override was the manager. The reconciliation was the manager. The customer trust, built over decades of branch visits and remembered children, was the manager.
For nine years, prosecutors allege, the manager spent it.
Allegation is not adjudication. The defendants are presumed innocent until proven otherwise in court. The case will be tried on the documents the prosecution can produce and the documents the defense can challenge.
But if you keep a sleepy account somewhere, an account in a foreign currency, an account you do not log into often, an account whose statement you glance at over coffee because the manager has known your family for years, do this before the weekend.
Open it. Read every line. Match every withdrawal to a memory.
The lock is only a lock if someone is checking it. Rozina Patelia, according to the charge sheet, was not checking. The bank, for nine years, was not checking either.
Somebody, eventually, has to be the one who checks.
That somebody is you.
