Dutch police have arrested eight suspected Islamic radicals as part of the investigation into the brutal slaying of outspoken filmmaker Theo van Gogh, prosecutors said Wednesday.
The suspects were detained in the 24 hours following Van Gogh's killing while he bicycled on an Amsterdam street, prosecution spokeswoman Dop Kruimel told the Associated Press.
Six detainees are of Moroccan origin, one is Algerian, and the other has dual Spanish-Moroccan nationality, she said.
The suspect in the killing -- a 26-year-old alleged Muslim extremist with dual Moroccan-Dutch citizenship -- was arrested Tuesday after a shootout with police.
Kruimel said the suspects were detained and released during an October 2003 investigation into a potential terrorist threat.
Van Gogh, 47, who received death threats after his recent movie criticized how women are treated under Islam, was repeatedly shot and stabbed to death on an Amsterdam street Tuesday.
