A hardline Islamist has been arrested in connection with the fatal shooting of a Tunisian opposition leader, a security source told Reuters.

The killing of Chokri Belaid on Feb. 6 outside his house sparked widespread protests across the country.

"The police arrested a Salafist suspected of killing Belaid," the source told Reuters Monday. Belaid’s brother could not confirm the report.

Last year, Salafists attacked the U.S. Embassy in Tunisia during protests over an anti-Islamic video, in addition to preventing concerts and plays from taking place -- claiming that they were violating Islamic principles, Reuters reports.

Belaid’s father led more than 3,000 Tunisians in a protest against what they called a “slow” investigation into the death on Saturday, according to the Associated Press.
