Police are appealing for information after thieves have targeted five homes in Bolsover for copper gas piping.
At around 6am on Tuesday morning, a woman on South Crescent was woken by a noise just after 6am and found that her boiler had stopped working. The outside gas meter had been turned off and copper piping had been stolen.
Similar incidents happened overnight on Friday and Saturday at houses on North View Street and Sherwood Street.
Pipes have also been cut, but not stolen, outside two properties on Cundy Road sometime overnight on Saturday and Sunday.
Community Safety Inspector Russ Dakin said: “Not only is this a huge inconvenience in terms of the cost of repairs but it could also be extremely dangerous. Residents are also being left without heating while they await repairs at a cold time of the year.
“We would urge anyone who may have seen anyone, or any vehicles, acting suspiciously around the area to come forward.”
Police have stepped up patrols overnight in Bolsover to help prevent and target offenders.
Residents are also advised to consider security marking any piping around their property using a forensic based gel or grease, which can act as a deterrent and help officers to catch any offenders.
Anyone with information about these incidents should contact Derbyshire police on 101, the non emergency number, or call Crimestoppers anonymously on 0800 555 111.
