Yaacoubi was freed and charges against him were dismissed, his lawyer Ghazi Mrabet said in a Facebook post.
Yaacoubi was sentenced to 21 months in jail in August for lyrics deemed offensive to police. He had performed the song during a concert.
After months on the run, Yaacoubi appeared in court in December, where his prison term was reduced to four months, a sentence which he appealed.
Fellow rapper Ahmed Ben Ahmed was also detained after the concert and served three weeks in prison in September-October. He was released Oct 17.
