Red light cameras: four in Colorado Springs and two in Pueblo on the north and south sides of town.

Police say they're making the streets safer and bringing in revenue for both cities.

Now crooks are using them too. They're calling you on the phone, claiming you were caught running a red light and time to pay your ticket is running out.

They're asking you to pay it now or a warrant for your arrest will be issued.

Folks we talked with say because the system's so new... they don't know how cities are collecting the fines.

One suggested, "If there's any doubt call and question the authenticity."

Another told us, "I have been a victim of fraud. It is the hardest thing to get off your record."

I'm told the crooks are smooth. They're asking for your credit card number, the card's security code, your birth date, as well as social security number.

But don't buy it. Colorado Springs and Pueblo police tell me they'll never call you on the phone to pay such a fine.

They don't need your social nor your DOB. They already have that info.

If you get such a call, ask the so-called cop for a description of your vehicle and your license plate number.

Better yet ask for a photo of both. That should get them to hang up and alert them to leave you alone.

Both Colorado Springs and Pueblo police say red light tickets are mailed out after officials have carefully checked the images taken by the cameras.
