Police shot and killed a suspect moments after he had stabbed a man in Mathare slums, Nairobi.
The stabbed man died of bleeding moments later, police said.
Witnesses said the suspect had chased the deceased man into a bar in the area and started stabbing him as a mob rushed to his help.
The motive of the Sunday night drama was not immediately established as both the suspect and victim died.
The assailant who police said was a notorious robber tried to escape while still armed with a knife as a mob bayed for his blood.
A mob pursued him and police joined the chase before shooting him a few meters away.
Police said he refused to heed an order to surrender.
