"Police need the public's help to limit opportunist thieves' access to vehicles by securing their property."
Police released the following prevention advice.
• Invest in an anti-theft system. These can range from a simple steering wheel lock to a full alarm system that will immobilise the car.
The type that is best for you will depend on how much you want to spend and how high the risk is for your car
• Giving the impression that you have an alarm system will sometimes be enough to deter thieves; stickers on windows or flashing LEDs on the dashboard can be all it takes
• Always lock your car, even when you are parked in your own driveway.
It can take mere seconds for a thief to drive away with your car – and the valuables you keep inside it
• Never leave your keys in your unattended car, even for a brief moment.
If you keep your house keys on the same keychain a thief could have both your car and access to your house
• Avoid leaving valuables like CDs, laptops, mobile phones, GPS devices and iPods in your car.
If you have to leave them there, make sure they are out of sight
• When you are parking at night you are more vulnerable to theft. Try to park in well-lit areas and always be aware of what is going on around you. Keep the doors locked at night even when you're in the car.
Be sure it is safe to get out if you are alone and it's dark.
