Three suspected robbers were shot dead on Sunday night after a gang broke into a godown in Kamakis area, Ruiru.
Kiambu county police coordinator Adiel Njagi said the gang cut through an electric fence and then scaled a wall.
They tied up watchmen before stealing items, including cosmetics, that belonged to Nice & Lovely.
The robbers loaded the items onto a truck that belonged to the factory as their accomplice waited in another one.
The CEO of the company learned of the attack through CCTV and called police; the three were killed in an exchange of fire.
The driver of the second truck fled in the vehicle but police pursued him.
A suspect was arrested and an AK 47 rifle found.
Three months ago, robbers broke into the godown and stole goods and three trucks, items which were not recovered.
