Issaquah police officers are increasing patrols in the business district to prevent thefts during the year’s busiest shopping season. Think of them as Santa’s backup.

They’re also out to warn shoppers if their vehicles and valuables are left too susceptible to prowlers and other Scrooges. If officers spot a high-risk vehicle — such as one with valuables visible to passers-by, they’ll place a gift tag on the windshield to warn the owner that he or she could become a prowler’s next target.

Those tags will let shoppers know that they’re on the naughty list, and offer information about shopping safely in the future. Here are some easy tips you can use to prevent crime from ruining your holiday cheer:

• Lock your vehicle every time you leave, even for a short time.

• Don’t leave valuable items in plain view.

• Don’t leave your vehicle running unattended.

• If you place items in the trunk, do it discreetly or before you arrive at your destination.

• If you see somebody acting suspicious or looking into vehicles, call police at 425-837-3200.

You’ll also notice a safety message from police at checkout stands in many Issaquah businesses.
