Police have been made aware of two incidents of catalytic converter thefts which occurred yesterday in Oldends Lane Industrial Estate, Stonehouse.
This is in addition to thefts being reported within car parks in Gloucester, Cheltenham, Stroud and Tewkesbury.
Police are requesting that communities are aware and stay vigilant.
Offenders are specifically targeting areas with car parks such as shopping centres, supermarkets, hospitals, railway stations and industrial estates.
Vehicles have been targeted at all times of the day, primarily in daylight hours, when catalytic converters can be removed in a matter of minutes.
The main vehicles targeted at the moment are Japanese manufactured cars such as a Honda Jazz or a Toyota Prius, although other vehicles are being targeted.
Victims only notice the crime after it has happened when they start their vehicle.
The public are advised to remain vigilant and report any suspicious behaviour, especially seeing cars being jacked up on the roadside and in supermarket car parks.
You should call 999 if a crime is in progress or if offenders are nearby.
Anyone who sees people acting suspiciously around vehicles should report it via 101.
CCTV or home doorbell footage can be sent through to help identify those involved.
Police are offering advice to motorists following a recent rise in catalytic converter thefts with incidents being reported across the county.
There are some protective measures drivers can consider to help reduce the risk to their vehicles. These include:
1) Park vehicles close to walls, fences, kerbs and garages with the exhaust closest to these, making gaining access to the underneath of the vehicle more difficult
2) Where possible park your car in a locked garage
3) Avoid parking your car partially on the pavement and if using a car park consider parking between other parked vehicles
4) Consider CCTV, security lights and alarms where possible.
5) Consider purchasing catalytic converter covers or clamps which are widely available and offer protection.
