A 53-year-old man from the village of Kitoben, Bomet, committed suicide after finding out that police wanted him.
The police issued an arrest warrant for the man who allegedly defiled his niece at the age of five.
Area Assistant Chief Philip Cheruiyot said the man, whose identity is yet to be revealed, had gone into hiding after the incident two weeks ago.
Cheruiyot said the deceased undressed beneath a tree where his naked body was found hanging.
His body was taken to Longisa Referral Hospital morgue.
Medical reports indicated that the minor was indeed defiled and that she had received proper treatment including medications to prevent HIV infection.
