His son, who was the factory's manager, was also arrested. Those killed ―35 of whom were women ―were trapped inside by locked fire exits, which were barricaded to stop theft during working hours. "The people who died were either asphyxiated or burned," commented a firefighter. 17 were wounded. Moustapha Taouil of the Casablanca civil protection service said the blaze was triggered by an inadequatly maintained electric saw on the ground floor.
