Journalist and historian Amadou Diouldé Diallo has been released after three months of pre-trial detention in a civil prison in Conakry.
Last month Diallo was charged with offending the Guinean head of state, Alpha Condé, whom he had strongly criticized in a prime-time show.
The veteran journalist will still have to pay a fine of 5 million Guinean francs ($500).
The court found him guilty of the charges against him.
