Detectives from the Directorate of Criminal Investigations (DCI) have arrested a top suspect in connection to Sh3.5 million robbery at Prime Bank along Mombasa Road.

The suspect was traced to his home in Githunguri, Kiambu when DCI officers nabbed him.

The arrest brings to four the number of suspects in police custody over the heist.

The suspects in custody include the two police officers who were guarding the bank and a teller.  The teller is helping the DCI with insights on the heist which was conducted in broad daylight.  

After the robbery, guns snatched from security guards were later disposed at a Kiambu hospital

Authorities believe that the suspect disposed of the guns which had been taken from police officers guarding the bank.

“The firearms were dropped by a motorbike passenger at Kiambu Hospital’s Gate shortly before the motorbike disappeared into the darkness,” DCI George Kinoti said.

Police are yet to locate the motorbike which ferried the suspect to the scene where the guns were found.

The investigation is being conducted by a team of DCI detectives from the headquarters, Embakasi and Special Service Unit officers.

During the robbery, a private security guard sustained injuries on his right arm.
