Born in Ziway, south central Oromia, he studied pharmacy at Addis Ababa University. One of the most charismatic and beloved leaders of the OLF, Nadhi was detained in 1994 by the Ethiopian security forces with a tip from another prisoner who was forced to disclose his whereabouts from torture. A report attributed to Hassan Ali, the President of the Oromia regional government at the time, later alleged that Nadhi was executed at the spot–somewhere at the intersection of three provinces–Arsi, Shawa, and Western Hararghe. Little is heard from him or the authorities since. There was a report that he was held in Mekelle, capital of Tigray region. According to some other reports, he was still being held at the notorious Maikalawi central prison.
