On the third day of a round of arrests of opposition politicians and activists, Tunisian police detained the head of a free radio station.
Officers searched Noureddine Boutar's home on Monday after he criticized President Kais Saied on Mosaque FM.
Numerous public figures, including an opposition politician, a well-known businessman, two judges, and a former diplomat, have been detained since Saturday.
According to Mr. Saied, he wants to avert chaos in the country of North Africa.
The detentions have been referred to as "kidnapping of Saied's opponents" by the largest opposition group in the nation, Ennahda.
Many Tunisians who backed President Saied when he took office in 2019 have recently turned against him.
Mr. Saied imposed his one-man rule by ousting the prime minister, suspending the legislature, and passing a new constitution in 2021.
A previous constitution that had been written soon after the 2011 Arab Spring uprisings, which saw Tunisia overthrow late dictator Zine al-Abidine Ben Ali, was replaced by the new one.
The executive branch is fully delegated to the head of state, who also has overall military command.
In the capital city of Tunis last month, tens of thousands of protesters gathered to call for the resignation of Mr. Saied's administration.
