METAL thieves are stealing catalytic converters from vehicles to sell on as scrap, police have revealed.
Eight incidents have been reported in North Derbyshire in the last two weeks.
A catalytic converter was stolen in the early hours of Wednesday from a Renault van parked on North Street in Langwith.
Thieves also targeted a Iveco Daily van parked in a yard off Nethermoor Lane, Killamarsh, in early hours of Tuesday.
Other incidents have been reported in Eckington and Duckmanton.
Sgt Paul Smith, of Derbyshire Police, said: “We would ask people to be vigilant and to contact us if they see anyone acting suspiciously around vehicles, especially vans and 4x4s.
“Information including descriptions of people or the cars they are travelling in could be key and could help officers to investigate any reports or thefts.”
Sgt Smith is urging vehicle owners to keep them in a locked garage if possible or a well-lit area if they have to be left outside.
Police are also suggesting residents install CCTV systems or security lights to cover driveways or garages.
The force said if catalytic converters are bolted on to vehicles, owners can have the bolts welded shut.
Protective coverings are also available for catalytic converters.
