Besides its fame as one of the leading slaughterhouses in the city, Kiamaiko is also a secret human trafficking hub, it has emerged.
It has emerged that the facility is now home to minors, sneaked into the country with the promise of a better life, only to be subjected to child labour.
Some of the labourers are children aged between 7 and 15, brought from neighbouring Ethiopia after their parents are hoodwinked that they are going to be educated in Kenya.
Abdi Yossef, 27, recounts he was brought to Kenya when he was only 7, and subjected into to child labour and forced to give out his pay to the trafficker, who, incidentally, happens to be his uncle.
"My uncle brought me to Nairobi when I was seven. He told my parents that he would take me to Kenya to educate me."
"I saw how other people who came to Kenya returned to build homes for their parents and I convinced them to let me go. Life here was completely different. My uncle brought me to Kiamaiko and sent me to work at the slaughterhouses," he says.
Yossef has since married a Kenyan girl but his life revolves around Kiamaiko as he fears arrest for lacking proper documentation to be in Kenya.
Emerging details indicate that the boys are smuggled into the country on lorries carrying goats, which are divided into two compartments; goats on top and the boys in the lower hidden compartment.
Once in Kiamaiko, their job includes herding animals, calling out customers, slaughtering the animals and cleaning the facility, most too young to understand Swahili.
Mariam Habiba, a Kenyan-Ethiopian human rights activist says that girls are also smuggled into the country and married off at tender ages.
This is after being brought in aboard trucks also used to smuggle small weapons and bhang, she says.
Habiba contends that attempts to seek police intervention have been futile since they are beneficiaries of the racket, a matter that has since been brought to the attention of Police Spokesman Charles Owino.
“We will first have to carry out preliminary investigations before I can give you an official statement. Give me some time," he said when contacted by the People Daily.
