The singer had been a rallying voice in anti-government protests that led to Prime Minister Abiy Ahmed taking power in 2018.
Angry protests followed his death on June 29, and authorities have said at least 239 people were killed. The military was deployed, and the Oromia regional police commissioner on Friday said nearly 5,000 people had been arrested.
The unrest has posed the most serious challenge yet for the prime minister, who was awarded the Nobel Peace Prize last year for his political reforms.
Human rights groups have openly worried that those reforms are slipping amid intercommunal violence and alleged abuses by security forces.
The internet remains cut off in Ethiopia after the singer’s killing, complicating efforts to track the latest unrest.
