The chemical is ammonium nitrate, a key ingredient in the bomb that destroyed the Oklahoma City federal building in 1995.
A nationwide alert was issued Monday by the Bureau of Alcohol, Tobacco, Firearms and Explosives after eight 50-pound bags of an ammonium nitrate-based explosive vanished from the Pike View Quarry near Colorado Springs.
The other theft, 700 pounds of an ammonium nitrate product, occurred Sunday or Monday from Tom C. Dyke Drilling and Blasting in Alpine, Calif., about 30 miles east of San Diego, authorities said. Thieves forced their way into a locked trailer and took 16 50-pound bags. Two of the bags have been found.
