Armed rangers, as well as Kenya Wildlife Service (KWS) vets with dart guns, scoured bush and agricultural land alongside the Kibera district, one of Africa’s largest slums.
At least two lionesses are reported to have late Thursday left the park, spread over 117 square kilometres (45 square miles) where buffalo and rhino roam just seven kilometres from the bustling high-rise city centre.
Local media reported as many as six lions might be on the loose.
