The Directorate of Criminal Investigations George Kinoti termed the Ksh14 million Barclays bank ATM heist an inside job.
Reports had indicated that cybercrime detectives suspect that three robbers might have jack-potted the ATMs to split money.
Experts have defined the jackpot technique as the use of electronic interference of an ATM machine, where hackers command it to release all its content.
The DCI's sentiments on the heist being an inside job came a day after the Head of Cyber Security at Internet Solutions Kenya, Bright Mawudor intimated that such a heist can only be effected in a well-coordinated inside job.

“An operational security risk where someone from the inside has been able to give access to someone from the outside,” Mawudor stated.
“Even if you manage to get to the safe you must have prior knowledge on ATM installation and software,” the cybersecurity expert added.
He explained that an ATM machine can go at rates of up to 50 notes every 20 seconds withdrawing thousands of shillings in one go.
DCI Kinoti, who spoke on Thursday further revealed that the investigations were at the final stages and they were hoping to bring the culprits to book.
Detectives attached to the DCI took over the case and detained five employees from the bank and G4S security group.
