TUNIS, Feb 26 (Reuters) - Tunisian police have identified the killer of an opposition politician, whose assasination this month sparked protests across the country, and have begun a manhunt, Prime Minister-designate Ali Larayedh said on Tuesday.
A security source said on Monday an extremist Islamist had been arrested in connection with the killing of Chokri Belaid on Feb. 6 which ignited the biggest street protests since the overthrow of strongman Zine al-Abidine Ben Ali two years ago.
Larayedh told reporters at a news conference on Tuesday that police had arrested three people belonging to the hardline Salafist movement. "Now we have identified the killer of Belaid and he is on the run. The police are looking for him," he said. (Reporting by Tarek Amara; Editing by Louise Ireland)
