A 60-year old woman and her grandson have been arrested after they were found with Sh2.3 million believed to part of the Sh72 million G4S heist.
Detectives from the Special Crime Prevention Unit, acting on a tip-off first arrested a suspect, John Kamau Mulei, at Muumandu town on Sunday night.
Police said Mulei is a brother to one of the suspects, Benard Mwendwa, who was arrested earlier on September 12.
Upon further interrogation, Mulei led the detectives to Kalimoni within Machakos County where the money was recovered inside his grandmother’s house.
The sexagenarian, Mary Kyalo, will on Monday morning be grilled by detectives as police try to establish if she played any role in the theft or hiding part of the loot for her grandsons.
The arrests bring to over 10, the number of people arrested so far over the armed robbery.
Some of the suspects who have been charged are: Chris Mochogu, Dancun Luvuka, Vincent Owuor, Boniface Mutua, Alexender Mutuku and Francis Muriuki.
The team, according to the detectives, had deeply infiltrated the G4S system and mastered the escort duties conducted by the Administration Police (AP).
Detectives said a phone data analysis played a key role in unraveling the theft.
A phone triangulation revealed that at least three phones were at Nairobi West and the owners went to the same direction from there.
The three phones, according to analysis, were all switched off at the Thogoto Forest, where the money bags were recovered.
The call data showed that strange numbers were now calling the suspects’ friends and relatives and the new numbers were used to track them down.
First to be arrested was arrested AP Constable Ayienda Machogu who was found with Sh4 million in Kisii.
AP Constable Ayienda is a graduate of the KCA University where he graduated in 2012 with a Bachelor of Commerce degree.
Upon interrogation, he led the detectives to Seka village in Kendu Bay, Homabay County where his accomplice, Owuor was found and arrested and a recovery of Sh3 million made.
