A source who sought to remain anonymous said they were in a vehicle and were escorting a lady friend to her house within Manyatta.

"One of the guys who was in their company asked the driver to stop to answer a call of nature," said the source.

It is at this point that unknown people attacked the other guy promoting the deceased to rush to his defense.

He was stabbed at the chest once and died on the spot.

"A confrontation ensued between the KDF guy and the other attackers then he got stabbed," he said.
