New Mexico ? Four men, including two brothers, were taken into custody Friday by federal authorities in connection with the theft of 400 pounds of explosives from a storage depot southwest of Albuquerque.

The explosives were reported stolen Sunday from Cherry Engineering’s storage depot eight miles southwest of New Mexico’s largest city. Federal authorities have said it was enough to flatten a large building.

The men, whose names were not immediately released, all face federal charges, including possession of stolen explosives.

Three of the arrests were made in Bloomfield, in the northwest corner of the state, and the other was made in Ignacio, Colo., said Tom Mangan, a spokesman for the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives.

Stolen were 150 pounds of C-4, 250 pounds of sheet explosives, 20,000 feet of detonator cord and 2,500 blasting caps.
