Kenyans took to social media early Tuesday morning to inquire the whereabouts of Billian Okoth Ojiwa, a vocal community leader in Mathare.

The youth in his 30s is said to have gone missing on Sunday at around noon. His wife Nerima Ojiwa has revealed she had filed a report at Kilimani Police Station on Monday and was told to return on Tuesday morning.

“He’s been missing since Sunday at noon; so, it’s been more than 24 hours without any contact whatsoever,” she said, noting that she will be more comfortable to share more details around the disappearance after talking with the officer handling the matter.

KANU party has appealed to members of the public to assemble at Kilimami Police Station from 9am so as to show solidarity to find Billian.

Billian is a community mobiliser who has established initiatives such as the Ficha Uchi Initiative which provides school uniforms for needy children especially in Mathare. Billian also helps children talented in music to record and sell their music through his foundation – Billian Music Family. His interest in leadership and politics have manifested through his vying for the Member of Parliament seat – Mathare constituency in the 2013 general elections. Billian is also an alumnus of Austria and Mandela Washington (YALI) leadership programs.

Billian’s disappearance comes barely week after Dandora activist Carol Mwatha disappeared. Ms. Mwatha is a founder member and a human rights activist at Dandora Community Social Justice Centre. The center seeks accountability among police officers and is against extrajudicial killings.

Amnesty International is among those who have appealed for the investigation of Ms. Mwatha’s disappearance by the police. Nairobi County governor, Mike Sonko, has promised to give a reward of Ksh300, 000 to anyone who has information on the whereabouts of the activist.
