Intelligence Assessment (Unclassified)
Prepared by the
FBI Criminal Intelligence Section
Copper thieves are threatening US critical infrastructure by targeting electrical sub-stations, cellular towers, telephone land lines, railroads, water wells, construction sites, and vacant homes for lucrative profits. The theft of copper from these targets disrupts the flow of electricity, telecommunications, transportation, water supply, heating, and security and emergency services and presents a risk to both public safety and national security.
Copper thieves are typically individuals or organized groups who operate independently or in loose association with each other and commit thefts in conjunction with fencing activities and the sale of contraband. Organized groups of drug addicts, gang members, and metal thieves are conducting large scale thefts from electric utilities, warehouses, foreclosed or vacant properties, and oil well sites for tens of thousands of dollars in illicit proceeds per month.

The demand for copper from developing nations such as China and India is creating a robust international copper trade. Copper thieves are exploiting this demand and the resulting price surge by stealing and selling the metal for high profits to recyclers across the United States. As the global supply of copper continues to tighten, the market for illicit copper will likely increase.
