The Bibb County Sheriff's Office is investigating a string of copper thefts from an unlikely source.
They say over the last month, thieves targeted at least a dozen lightposts along I-75 and I-16 near the interchange.
Thieves broke into the bases of the poles and took out a total of more than 3,000 feet of copper wiring, then stripped it so it would look like any other wiring to sell.
Because extracting the wiring means pulling it from the underground connections between poles, Investigator John Horne says he believes the thieves have expert knowledge of how the electronics work.
The thieves may have posed as maintenance workers or as someone broken down on the side of the road to avoid suspicion.
Meanwhile, local scrap shops say they're already on alert for suspicious activity.
Price Williams of Peacock's Recycling says red flags usually include someone coming in with a large amount of copper.
He says he takes a picture of everyone coming in to sell metal so it can be reported to police in case metal is found to be stolen.
The value of the copper in this case was estimated at around $2,000.
Macon-Bibb maintenance workers say they're still working to get the lights fixed.
