WICHITA, Kan. (AP) -- Wichita police say they've found evidence of a significant identity theft operation.

Police Lt. Clark Wiemeyer says a Sedgwick County sheriff's deputy found a half-dozen fake IDs and numerous stolen checkbooks when after he stopped a car Wednesday.

The 35-year-old driver was arrested on an outstanding warrant. The deputy contacted Wichita police after discovering fake IDs.

Wiemeyer says thieves are stealing checkbooks or other forms of identification, then making fake IDs to use with the stolen checks.

Investigators found paper for making fraudulent checks at the homes of the driver and a second person. Wiemeyer says the suspects worked hard to make their IDs look authentic, and were also printing fake checks.
