"Political prisoners that are facing prosecutions and are already under arrest will be released", Prime Minister Hailemariam Desalegn said at a press conference, according to The Associated Press.
Desalegn also disclosed the shutting down of the notorious detention center, known as Maekelawi, which had been serving as Ethiopia's main investigation center since the Derg regime.
Some of the prominent politicians now in custody include opposition leaders Bekele Gerba and Merara Gudina, and several journalists also remain in detention.
Its 547-seat parliament does not have a single opposition politician in it, and opposition groups accuse the government of constant harassment and intimidation.
"A new chapter for human rights will only be possible if all allegations of torture and other ill-treatment are effectively investigated and those responsible brought to justice".

The move comes in the wake of widespread anti-government protests that engulfed much of the restive Oromia and Amhara regions and other towns and cities.
"It was absolutely not clear what the prime minister was saying", said Yacob Hailemariam, a lawyer in Addis Ababa, the capital. Human Rights Watch had alleged that Maekelawi, a detention facility in Addis Ababa, was used to conduct illegal interrogation methods in 2013.
