A former G4S security guard has been jailed after wearing his old uniform to trick Santander staff into handing him £117,200 in cash from a London branch.
The Independent reported that Kwabena Kissi, 40, walked into a Santander branch in Brixton, south London, in July 2022 while wearing a G4S uniform, helmet, mask, and visor. CCTV footage showed him entering the bank before staff handed over bags of cash.
The deception worked long enough for Kissi to leave with the money. Staff realized they had been fooled only after the real G4S guard arrived for the scheduled collection.
Kissi admitted fraud by false representation at Snaresbrook Crown Court and was sentenced to 40 months in prison.
Staff Thought He Was Early For A Cash Collection
LBC reported that Kissi had worked for G4S as a guard between 2019 and 2020. When he resigned, he failed to return his uniform.
Prosecutors said Kissi arrived at the Santander branch dressed like a legitimate cash custodian and was allowed into a secure area behind the front counters. When a staff member said he was “a little early,” Kissi claimed he was on a new route.
Otis Williams, the bank branch’s vault manager, told investigators that he had prepared £256,000 in 11 bags for collection that morning, according to LBC. Kissi left with £117,200 of that total.
The Real G4S Guard Arrived After The Money Was Gone
Staff recognized the fraud after Kissi failed to return for a second pickup and the genuine G4S custodian arrived nearby, according to court reporting cited by LBC and The Independent.
After leaving the branch, Kissi changed out of the uniform and was seen carrying a black bin bag containing the cash. He then booked an Uber to leave the area.
Investigators said the Uber booking linked him to the getaway because he used his own name and phone number. Detective Constable Stuart Ponder, who led the Metropolitan Police investigation, said officers identified Kissi through extensive CCTV work and phone evidence tied to the minicab.
He Flew To Ghana The Next Day
The day after the Brixton bank fraud, Kissi flew to Accra, Ghana. The Times reported that he lived there with his ailing mother for nearly four years.
Kissi was arrested after returning to the United Kingdom in March 2026. LBC reported that he initially claimed police had mistaken him for someone else.
Officers later found that he still had the same phone he had used during the 2022 fraud, according to LBC’s report on the investigation.
The Judge Said He Used Inside Knowledge
At sentencing, Judge Rosa Dean said Kissi had exploited his inside knowledge of the bank process. The Times reported that she also noted the effect on Santander staff, who feared they could lose their jobs after the deception.
LBC reported that no Santander employees were disciplined. Kissi’s defense said he had gone to Ghana to care for his mother, while prosecutors and the judge focused on his flight from the United Kingdom after the fraud.
Kissi was sentenced to 40 months in prison after admitting fraud by false representation.
Uniforms Are Not Verification
Kissi did not need to break into a vault or hack a banking system. He relied on an old uniform, a familiar collection routine, and enough knowledge of cash pickup procedures to look like the person staff expected to see.
Businesses that hand over cash, records, keys, deposits, equipment, or high-value goods should verify the collector through a separate process before releasing anything. A uniform, badge, helmet, branded bag, or confident explanation should not be enough.
Secure pickups should use active schedules, pickup codes, photo identification checks, callback procedures, and confirmation through a trusted contact. Former employees should also be required to return uniforms, badges, keys, access cards, and branded equipment when they leave.
Employees should pause when a collector arrives early, claims a route changed, changes the pickup process, or cannot be verified through the normal system. A short delay is safer than releasing cash to someone who only looks the part.
