Inspector General of Police Joseph Boinnet announced that 21 people had lost their lives in the heinous attack at Dusit hotel complex.
Speaking during a presser, the IG of police said six more bodies were found at the crime scene.
The IG also stated that one police officer was also among the people who lost their lives in the attack after succumbing to injuries while undergoing treatment.
21 dead
The 21 people included 16 Kenyans, one Briton, one American national and three persons of African descent who are yet to be identified.
Notably, 28 people were wounded during the attack and were admitted to various hospitals in Nairobi.
During the presser, IG Boinnet confirmed that the Directorate of Criminal Investigations had arrested two suspects who are key in the ongoing probe.
DCI Kinoti said the suspects were arrested in Eastleigh and Ruaka estates where one of the attackers lived.
Suspects in custody
According to the DCI, the suspects were providing information on the incident since they were allegedly in contact with the slain men.
Sleuths who visited the house of one of the slain terrorists in Muchatha said they recovered bomb-making material and disabled another one which had been assembled halfway.
Detectives visited the police control room at Jogoo House for data on the movements of the car that was used to ferry the terrorists to the site while others visited apartments near Dusit complex to check if there would be more suspects hiding there.
It is not clear how they were brought into the country. The grenades used in the attack were also taken for analysis.
