Tunisian police on Monday arrested Noureddine Bhiri, the senior official in the main opposition party and a fierce critic of President Kais Saied, a lawyer said.
"The police stormed Noureddine Bhiri's house, assaulted his wife, and arrested him,," his lawyer, Samir Dilou, told Reuters without giving any further details.
During the last two days, police have carried out a wave of arrests that included prominent politicians and a powerful businessman, for being suspected of plotting against state security.
