Thieves take thousands of dollars worth of copper from some construction sites in Pikeville.
Police say they have worked at least five cases in the past month.
The latest theft happened Friday morning at a site on South Mayo Trail.
Pikeville Police say sometime during the overnight hours, thieves took six rolls of copper wire, at least five rolls of copper tubing, and tools. It adds up to an estimated $5,000 worth of equipment.
"We're still investigating but it took awhile to get that stuff out with that kind of weight and the amount of stuff they did take, it took awhile to get it out of the building," said Officer Tony Conn.
This is the latest in a string of copper thefts in the city.
"It's mostly new construction sites, what they seem to be hitting the most," said Conn.
Investigators say thieves have taken copper from at least five places in the past month.
There are no arrests yet.
"Most have the same M. O., took the items out, left the scene with really no trace of evidence behind," said Conn.
While detectives look for suspects, other officers and construction contractors are taking action in an effort to prevent more copper thefts.
"They're taking measures to increase their security to ensure this type of theft doesn't happen again, especially at this location. We're increasing police patrols to ensure this does not happen again," said Paul Maynard, Pikeville Public Safety Director.
Neighbors are asked to report any suspicious activity around the construction areas.
Anyone with information or tips on the copper thieves should contact the Pikeville Police Department.
