Hundreds of people have marched through the Kenyan capital to protest at the brutal killing of an HIV-positive boy.
Aids activists are outraged at the killing
Isaiah Gakuyo was allegedly stabbed to death with a pitch-fork because of his status. Police are hunting his uncle, who was supposedly looking after him.
Mr Gakuyo's mother and grandmother had both reportedly died from Aids-related illnesses.
Aids activists say the killing highlighted the stigma faced by those living with HIV/Aids in Kenya.
At one point, he was looked after by members of Nobel laureate Wangari Maathai's Green Belt Movement after he had reportedly been mistreated by his uncle.
The Kenya Times newspaper reports that the boy had to use separate eating utensils from other members of the family.
At his funeral, Aids activists urged the police to find the killer but two weeks later, no-one has been arrested.
"The boy was facing violence on a daily basis," Inviolata Mwali Mmbwavi, one of the march organisers, who runs a group working with Kenyan Aids victims, told Reuters news agency.
"We don't want this to happen again."
