Ennahda described the seizure of Noureddine Beheiry as a “dangerous precedent” that threatens to slip toward “tyranny”.
Tunisia’s Ennahda movement said security forces had detained a prominent party official, denouncing what it described as an illegal attempt to silence the country’s political opposition.
And in a Facebook post, on Friday, the party with the largest number of seats in the suspended Tunisian parliament said that agents in civilian clothes had transferred Noureddine Al-Behairi and his sister-in-law, lawyer Saeed Al-Akrami, to an unknown destination.
“The Ennahda movement strongly condemns this dangerous precedent that threatens the country’s entry into the tunnel of tyranny and the suppression of political opposition outside the framework of the law,” the statement said.
President Kais Saied sacked parliament and seized power in late July in a move his opponents described as a coup.
Since Said’s intervention, many senior politicians and business leaders have been arrested or prosecuted, often involving corruption or slander cases.
A Tunisian court on December 23 sentenced former president and Saeed critic Moncef Marzouki in absentia to four years in prison for “assaulting” state security, according to state media.
In a statement to Al-Jazeera, Al-Marzouki rejected the ruling and described it as illegal, saying that “it was issued by an illegitimate president who overturned the constitution.”
Human rights groups have criticized some of the arrests and the use of military courts to try such cases.
Said denied the allegations of the coup and promised to support the rights and freedoms achieved by Tunisia’s 2011 revolution that ushered in democracy and unleashed the Arab Spring uprisings across the region.
However, the former constitutional law professor has ignored the 2014 democratic constitution, granting himself powers to govern by decree during a transition period during which he will put a new constitution to a public referendum.
Ennahda was banned before the revolution, but then it became the most consistently influential party and a member of successive coalition governments.
The party’s support has recently waned due to economic stagnation and the paralysis of its political system.
