A second fire broke out Thursday morning at a key aluminum supplier to Ford and other automakers. A Sept. 16 fire at the plant reduced production of F-150 pickups and other models. Thursday’s fire appears to be in the same area of the plant, said people familiar with the matter.

The Bureau of Alcohol, Tobacco, Firearms and Explosives said Wednesday it has taken the suspect, Lawrence Reed, into federal custody in connection with the attack.

Fire officials ordered the evacuation of the entire site for the conference, known as COP30, and it wasn’t clear when the talks would resume.
