A former private security guard has been sentenced to three years and four months in prison after impersonating a cash collection officer to steal £117,200 from a Santander branch in south London before fleeing the United Kingdom.
Kwabena Kissi, 40, admitted carrying out the fraud after exploiting his previous employment with G4S, where he had worked between 2019 and 2020.
Prosecutors said he relied on knowledge gained during his time with the security company to convince bank staff that he was a legitimate cash collection officer.
CCTV Captured the Entire Fraud
Footage presented to Snaresbrook Crown Court showed Kissi arriving at the Santander branch in Brixton on July 5, 2022.
Wearing his former G4S uniform, a protective helmet with the visor lowered, and a face covering, he carried a large security briefcase into the bank.
Believing he was the scheduled security courier, employees granted him access to the secure cash handling area. Staff then loaded bags containing £117,200 into his briefcase without suspecting anything was wrong.
After leaving the branch, CCTV later showed Kissi changing his clothing before transferring the stolen cash into a bin bag. He subsequently ordered an Uber and left the area without raising immediate suspicion.
Staff Realised the Fraud After Genuine Collection Officer Arrived
The deception only became apparent when the legitimate G4S courier reached the bank to perform the routine Tuesday cash collection.
According to prosecutor Imogen Nelson, one employee had initially remarked that Kissi had arrived earlier than expected. Kissi reportedly responded that he had been assigned a new collection route, a statement that reassured staff at the time.
The prosecutor told the court that nothing about his behaviour appeared unusual, as he followed the normal procedures expected of a G4S custodian while collecting the cash bags.
More Than £117,000 Taken From Cash Collection
Evidence presented during the trial revealed that vault manager Otis Williams had prepared approximately £256,000 across 11 cash bags for collection that morning.
Kissi ultimately made off with £117,200 before leaving the bank. Employees became increasingly concerned when he failed to return for an additional collection, with suspicions confirmed after the genuine G4S security officer arrived shortly afterward.
Escape to Ghana Delayed Investigation
The day after the theft, Kissi boarded a flight to Accra, Ghana, where he remained for nearly four years.
His defence lawyer, Piers Walter, argued that his client travelled to Ghana to care for his seriously ill mother, who was facing severe financial hardship and later died from heart failure.
However, Judge Rosa Dean said the available evidence suggested his departure was intended to avoid detection rather than provide family care.
Simple Mistake Led Detectives to the Suspect
Investigators eventually identified Kissi through extensive CCTV analysis and mobile phone evidence connected to the Uber journey used during his escape.
Crucially, he had booked the ride using his real name and personal telephone number. When Kissi returned to Britain on March 26 this year, officers arrested him upon arrival at Gatwick Airport.
Although he initially claimed police had arrested the wrong individual, detectives recovered the same mobile phone that had been used to arrange the getaway vehicle nearly four years earlier, strengthening the evidence against him.
Court Hears Employees Were Deeply Distressed
During sentencing, Judge Dean said Kissi had abused his insider knowledge from his previous employment to execute the carefully planned fraud.
She noted that employees at the Santander branch had been left extremely upset by the incident, expressing relief that none of them ultimately faced disciplinary action because of the theft.
One long-serving Santander employee, Marlon Louis, said in a statement that the incident had left him devastated and fearful for his career after 25 years with the bank.
Guilty Plea Brings Case to an End
Kissi, who has no fixed address, pleaded guilty in April to fraud by false representation after using false identification to obtain the cash.
A separate allegation of possessing criminal property was later dropped after he denied the offence.
Police Say Persistence Secured Conviction
Detective Constable Stuart Ponder, who led the Metropolitan Police investigation, said officers never abandoned efforts to locate Kissi despite his departure from the UK shortly after the crime.
He said investigators traced the suspect through CCTV footage and phone records linked to the Uber used as his escape vehicle.
After learning that Kissi had travelled abroad, officers monitored developments until his return, when he was arrested immediately after landing.
The detective said the case demonstrated the Metropolitan Police’s determination to pursue high-value theft investigations and bring offenders to justice regardless of how much time had passed.
