Motorists have been warned to be vigilant against criminals targeting catalytic converters.

Police in South Norfolk are to conduct extra patrols after a series of night-time incidents in Harleston, Roydon and Scole where suspects targeted vehicles.

'Unfortunately, with the cost of scrap metal, this sort of crime can be quite common in rural areas,' said Chief Inspector Stuart Armes, policing commander for South Norfolk.

'We are urging drivers to take extra precautions whenever possible to try and reduce their chances of falling victim to catalytic converter theft.

'We will also be targeting patrols in these areas.'

The incidents included a Ford Ranger being targeted on a forecourt in High Road, Roydon and a converter being stolen from a Citroen Relay van in Pretty Drive, Scole.

A Peugeot 406 was targeted in Wildnerness Close, Harleston.

All incidents happened over the evening of Thursday and Friday.

Chief Insp Armes added: 'Parking parallel to another vehicle can make access difficult.

'It's best to keep your vehicle in a garage if possible - and ensure it is fitted with an alarm.

'Security marking your catalytic converter can be very effective and can help to identify it as a stolen item.'

Officers are also advising people to use alarms, lighting and CCTV to deter thieves and remove all valuable items from their vehicles.

Those who cannot keep their vehicles in a garage are advised to leave them in a well-lit, public area.

Those who may have witnessed the thefts in Harleston, Roydon and Scole or noticed anything suspicious in those areas at the time should contact Norfolk Police on 101.

Alternatively people can call Crimestoppers anonymously on 0800 555 111.
