Israeli police on Tuesday arrested Sheikh Raed Salah, leader of the Islamic Movement in Israel, from his home in the northern city of Umm al-Fahem.
"Salah was arrested and interrogated on suspicion of inciting acts of terror and supporting an unlawful organization," police said in a statement.
He was arrested following a joint investigation between police and the Shin Bet, which was conducted at the behest of Israeli Attorney General Avichai Mandelblit, it added.
The statement said since the Islamic movement was outlawed, Salah spoke to the public and published a series of statement in the media regarding the movement's views.
Salah's Islamic Movement was outlawed by Israeli authorities in 2015. Ever since, Israeli authorities detained Salah several times and shut down dozens of organizations -- including a number of charities -- over their alleged links to his group.
Israel, meanwhile, has prohibited Salah, who is seen as an icon of the Palestinian resistance, from traveling outside the country for reasons ostensibly related to "national security".
