Community mobilier Billian Okoth Ojiwa who had been reported missing since Sunday noon has been found.
His wife Nerima Wako-Ojiwa, the CEO of Siasa Place and a columnist with The East African, shared the good news on her Facebook page. "We found Billian thank you so much," wrote Nerima.
Joseph Towett, the Kanu national executive director had earlier said: "The information we have is that Billian is in touch with the family members and the same has been reported to the police and therefore we'd give police time to find out the circumstances that came out of that social media circulation."
He is said to have told his friends that he went to the Retreat Centre in Karen to "cool off".
Mr Ojiwa, who is in his early 30s, is best known for the Ficha Uchi Initiative, a programme he founded that gives school uniforms to needy children.
He is also the chairman of the youth congress of the Kenya African National Union (Kanu).
Earlier, his wife told Nairobi News that she was with him at her parent's house on Sunday when he stepped out at around noon.
Ms Wako said he walked out without carrying most of his possessions.
"He didn't have his phone, his car keys or his office keys. I thought he had gone to the shop. I haven't seen him since then," she said.
