Hailu Shawel, the head of the Coalition for Unity and Democracy, says police will not let him heave his house.
Witnesses say several journalists who tried to go to his home Saturday were roughed up by police, and had their equipment confiscated.
Mr. Hailu's detainment comes despite an agreement Friday between the government and opposition parties to work together to end recent violence sparked by election results.
Wednesday, police opened fire on protesters in the capital, Addis Ababa, killing at least 26 people. A teenage girl was also killed Monday during protests at a university.
The protesters say the ruling party rigged parliamentary elections last month. Preliminary results show the ruling party has won a majority of seats.
