PEORIA, Ill. (AP) — Illinois lawmakers have convened a task force to investigate a spike in the theft of recyclable metals.

Thefts peaked a few years ago when the price of copper and other recyclable metals rose. Copper wiring and pipes have been ripped from homes, signs and air conditioners have been stolen, and even metal grates over storm drains have been taken.

Bartonville Police Chief Brian Fengel tells the (Peoria) Journal Star that the Recyclable Metal Theft Task Force is working with law enforcement, utilities, the scrapping industry and insurance associations to determine how the thefts can be reduced. Fengel sits on the task force and says a report is due in the fall.

Potential ideas are enforcing tougher prosecution and establishing better lines of connection between scrap yards and police.
