Ethiopia's former deputy intelligence chief has been arrested amid investigations into corruption and human rights abuses committed by the security forces.
Yared Zerihun, the former deputy head of the national security agency, is one of more than 60 intelligence and military figures arrested since Monday.
Mr Yared has not yet commented on the allegations.
The move has been widely welcomed by human rights groups.
Ethiopia's Prime Minister Abiy Ahmed promised a strong line on corruption and human rights abuses when he came to power in April this year and has passed a string of reforms, including ending a two-decade conflict with neighbouring Eritrea.
