Four hardcore criminals were on Monday shot dead by police in Baraka area of Mowlem, Dandora.
A police source said the ringleader identified only as Mutuku and his accomplices had been on the run for a long time.
"They have terrorised Nairobians from all corners of the city; Mukuru, Kitengela, Kayole, Buruburu, Kasarani, Ruiru and Thika."
According to the source, the suspects were shot dead by the revered crime buster Ahmed Rashid, popularly known as Hessy.
The gang has been captured several times on CCTV committing robberies, particularly in M-Pesa shops.
On October 17, Rashid arrested one of the city's notorious criminal named Brayo.
The youthful gangster is wanted for a series of robberies and murders in the city including that of Corporal Martin Korir who was killed during the hijacking of a Neo Kenya bus on Thika Road on April 28.
Four gangsters believed to have participated in the murder were killed on May 12 in Dandora Phase 2 and a gun belonging to the slain cop recovered by Flying Squad officers.
