OMAHA, Neb. (AP) — Authorities in eastern Nebraska say two men stole copper found in a vehicle.

The Douglas County Sheriff’s Office says 23-year-old Matthew Polsley and 51-year-old Tracy Corey have been charged with felony theft.

A surveillance team stopped the men Tuesday night while they were in a pickup. Authorities say the pickup had copper loaded in the back. It was later valued at more than $500.

Authorities say the department has investigated several reports of copper theft over several months. It’s unclear if there is a connection to the men.

Court records do not list attorneys for them.
