In a significant breakthrough, law enforcement authorities have apprehended a primary suspect in the brutal killing of DCI detective David Mayaka, shedding light on the chilling incident that shook the nation.

The arrest came as part of a meticulously planned operation conducted by the elite Crime Research & Intelligence Bureau based at the DCI Nairobi regional command.

The suspect, Alex Wanjiru, aged 23, was a key member of the gang responsible for the cold-blooded murder of Detective Mayaka.

Wanjiru had managed to evade capture by fleeing to his grandmother's residence in Ruthingiti, Kikuyu sub-county, Kiambu County, following the tragic event. The diligent work of the CRIB sleuths eventually exposed his hideout.

Earlier investigations led to the impounding of the motorbike that served as the getaway vehicle during the night of the murder.

The bike, a red Boxer with registration number KMGJ 350V, was linked to the assailants through meticulous forensic analysis.

This evidence placed the suspects at the crime scene during the exact time of the incident.

Further examination conducted by ballistic experts at the DCI National Forensic Lab revealed a startling connection between the firearm used in the fatal shooting, identified as a C2, and five previous robbery cases within the city.

This discovery points towards a potential series of criminal activities undertaken by the same group of criminals.

As the investigation continues to unfold, two additional individuals have been identified as accomplices in the heinous murder.

The prime suspect, Henry Njihia, who allegedly fired the shots that claimed Detective Mayaka's life, and John Kamau, also known as Faruk, armed with a glock pistol, complete the trio of individuals involved in this tragic incident.

Intensive efforts are underway to locate and apprehend Njihia and Kamau.

Law enforcement officials have confirmed that both individuals are under close surveillance, and their apprehension is deemed imminent.

The heart-wrenching incident unfolded on August 8th, around 10pm, when Detective Mayaka, based at DCI Makadara, was driving home with his wife, Kemunto Mayaka. The couple was accosted by a gang of three individuals riding a motorbike.

The shocking scene was captured by CCTV cameras installed at a nearby building. Mayaka had halted his vehicle to address a flat tire, a moment that was exploited by the criminals to execute their deadly assault.

As the investigation presses forward, the collaborative efforts of the CRIB sleuths and forensic experts bring the nation one step closer to uncovering the truth behind this tragic event.

The arrest of Alex Wanjiru represents a significant milestone in the pursuit of justice for Detective Mayaka, as authorities inch closer to unveiling the full scope of the criminal network responsible for a series of robberies and the senseless loss of a dedicated law enforcement officer's life.
