"Don’t let the grinch steal your Christmas, be vigilant this summer."

That's the message from Sergeant Paul McRoberts.

As the weather ramps up so too can opportunistic crime, with people out and about more and thieves eyes wandering - cars and properties can become a target.

Police are aware of three cases in Hamilton in the past week where bank cards have been stolen from inside vehicles.

In one case more than $20,000 worth of items was taken from the vehicle including tools, a radar detector, an iPhone and two heat pumps.

Almost $1000 was spent across six transactions using three separate cards stolen from the three vehicles, says Paul.

"Police are also aware of several packages being stolen from doorsteps and visible spots on private property.

"In two cases packages were stolen from the front porch of properties in Enderley and Baverstock.

"Waikato Police are making inquiries in the five above cases, including viewing any available CCTV footage, and speaking to any witnesses.

"We know how stressful the lead up to Christmas can be and we want to equip you with some tools to prevent yourself, your car or your house from becoming a target.

"With Christmas shopping ramping up and increasing online purchases, ensure you have your packages delivered to a secure location like your workplace, the rear of your property, or select a time you will be at home for delivery.

"We need your help to try to reduce the opportunities thieves have to target you."

You can protect yourself by:

•             Take valuable items and important documents out of your vehicle. 
•             Always lock your vehicle.
•             Park in a well-lit area – or better yet a garage.
•             Consider installing security cameras.
•             Consider installing a vehicle alarm, if it doesn’t already have one.
•             Get packages delivered to a place where someone will be home to receive them, or to a work address.
•             If you do have deliveries made to your home, make sure you're going to be home, or have a secure location where they can be left.
•             Be smart when disposing of packaging, so passers-by can’t see if you've been buying expensive items.

If you see any suspicious or illegal activity or are a victim to theft, try noting as much detail as possible and contact Police on 111 if it’s happening now or 105 if it’s after the fact.

Keep your items protected this summer and stay vigilant.
