WILLISTON, N.D. (AP) — Williston police say the number of copper thefts is increasing in the city.

The Williston Herald reports that one business recently reported the theft of 400 feet of copper that was worth $15,000.

Det. Cory Collings says numerous copper thefts have occurred at scrap yards, vehicles and construction sites.

North Dakota recently imposed new regulations on scrap metal purchases. Scrap metal dealers now must keep a record of any transaction involving more than $25 worth of scrap metal, including details of the type and amount of material involved.

The regulations do not apply to beer kegs, food and beverage containers or wrecked cars.
