Detectives have unmasked the mastermind of the infamous Mulot SIM swap syndicate, one David Mutai alias Hillary Langat Matindwet.

According to the DCI, Matindwet is a dangerous criminal who has previously served time in prison and has several cases and warrants of arrests hanging around his neck.

This follows comprehensive investigations by the detectives based at the elite Crime Research & Intelligence Bureau, who unraveled the identity of the de facto leader of the criminal enterprise, responsible for SIM swap scam.

In a recent case leading to the arrest of two of his accomplices, the scammers had siphoned Ksh 941,000 from a bank account belonging to a legislator from Rift Valley between December 2 and 3 this month.

Following the incident reported by the legislator, one of Mutai’s lieutenants Justus Rono, 28, was arrested in Mulot.

Rono, who disguises himself as a boda boda rider is one of the main suspect’s trusted allies, who ferries him on his bike discreetly to avoid detection from our hawk-eyed sleuths.

Images of Rono showing off wads of cash following some of the successful operations that they have conducted, were also obtained by the detectives.

A second suspect identified as Kevin Kiplagat, was also apprehended at Sigor market, Bomet County, in the latest arrest of SIM swap fraudsters who have sought refuge in the infamous trading centre that has gained notoriety for harbouring cons.

The DCI claims that the fraudsters have also perfected the act of impersonating senior government officials and obtained an unspecified amount of money from unsuspecting members of the public.

The suspects who have registered multiple SIM cards using details from fraudulently acquired identification documents, deposit the siphoned money to different Mpesa accounts, in a bid to make it difficult for detectives for track them down.

In most instances, the fraudsters working in cahoots with rogue banking officials pose as customer care agents from banks then ask for a customer’s account number, PIN, as well as details of the last transaction on the targeted account.

They then use the details to duplicate the victims’ account and after a successful SIM swap, the account is swept clean in a matter of seconds.

Local financial institutions are the most targeted due to their inferior network segmentation systems, that expose their clients’ sensitive data to the fraudsters incase of cyber threats.

As a precautionary measure, Kenyans are requested not to reveal their national identity card name and number, the last time they made an M-Pesa transaction and the amount, the last airtime top-up and amount and the Personal Identification Number of their sim cards to strangers who contact them.

Meanwhile, detectives have launched a manhunt for David Mutai alias Hillary Langat Matindwet.
