Police have arrested one of the main suspects behind the killing of Directorate of Criminal Investigations (DCI) detective David Mayaka in Kayole last week.
The suspect, 23-year-old Alex Wanjiru, was arrested in Ruthingiti, Kiambu County by sleuths from the Crime Research and Intelligence Bureau based at the DCI Nairobi regional command centre.
“Alex Wanjiru, 23, who was part of the miscreant gang involved in the cold-blooded murder of our colleague detective David Mayaka, had escaped from Kayole immediately after the incident and sought refuge at his grandmother’s home in Ruthingiti, Kikuyu sub-county before detectives tracked him down,” DCI said in a statement.
DCI has also announced that they have impounded the motorbike used by the suspects on the fateful night, a red Boxer registration number KMGJ 350V.
Detectives have also linked the firearm used in the killing to five previous robbery incidents in Nairobi city.
“A comprehensive analysis conducted by ballistic experts based at the DCI National Forensic Lab has since linked the firearm that fired the fatal shot a C2, to five previous robbery incidents in the city,” DCI added.
The police are tracking down two other suspects, Henry Njihia who is believed to have fired the shots that killed Mayaka and John Kamau aka Faruk, who is also believed to be armed with a Glock pistol.
Mayaka, who was based at DCI Makadara was driving home in the company of his wife Kemunto Mayaka on August 8, at around 10 pm when they were accosted by the three-man gang riding on a motorbike.
The officer had stopped his vehicle to change a flat tyre when they were attacked, an incident captured by CCTV cameras at an adjacent building.
