The arrests throughout the country were tied to Sunday's clashes in the Tunis suburb of Ettadhamen, officials said.
The Interior Ministry presented the final tally Tuesday during a news conference, Tunisia Live reported. Ministry spokesman Mohamed Ali Laroui said cartridges, uniforms and nerve gas containers were confiscated.
Among those arrested was Ansar al-Sharia spokesman Seifeddine Rais, who said the organization that advocates implementation of Sharia law, planned to protest in front of the headquarters of the ruling Ennahda Party Friday as a show of support for those arrested, Tunisia Live said.
On Tuesday, the Interior Ministry outlawed Ansar al-Sharia and banned all of its activities.
