Police are asking for the public’s help to find a man who stole nearly $800 worth of teeth whitening strips from a Littleton CVS last June and brazenly came back to the store again this month for a second heist.

The suspect reportedly swiped 16 packs of the expensive cosmetic product during his first trip to the pharmacy, and was recognized by an employee during his second attempt this month.

After observing the man packing his cart with white stripes, an employee reportedly confronted the would-be shoplifter, who then ran to a nearby getaway car.

The crime may seem weird, but there’s a serious black market for the products, which can range from $25 to over $50 a piece in stores.
