A couple is being held by police after their seven-month-old boy was sodomised and abandoned in their house.
Area County Children's Director Fred Simi said his officers were alerted by members of the public to a child crying in the house and when they went to check, they found the child naked and frail.
"We found the boy with wounds on his buttocks, indicating that the heinous act had been going on for some time," said Mr Simi.
He said the minor seemed to have been left for about four days without food, adding that they took him to Narok County Hospital where after a medical examination, he was found to have been infected with a viral disease.
Area OCPD Paul Kiogora said investigations were ongoing. The child will be taken to a children's home once he is discharged from hospital.
