Police have intensified the crackdown against members of the Oromo Liberation Army (OLA) in Marsabit and Isiolo.
This is amid reports that the Ethiopian renegade gang was threatening Kenyans it suspects of spying on them.
It also emerged that some members who have ditched OLA are living in fear and have sought refuge in Nairobi.
A security source said the former OLA members claim that they have been issued with death threats. "They are being held in safe houses here in the capital city as we explore ways of removing them from harm's way," said the source.
