Copper thieves broke into a storage unit Saturday night on the South Anchorage property of Klebs Heating, Plumbing and Air Quality, presumably looking for scrap copper stored inside.

Crystal-clear security camera footage caught the two males entering the unit after breaking the lock. In the video, the two "high-five" each other -- then one of them then spots the camera out of the corner of his eye, and puts his hand over the lens.

A security alarm scared the duo off before they could take anything.

Klebs says it's the sixth time its property has been broken into, but store officials hope someone can recognize the people who did it this time.

"It's kind of a moral victory to get this kind of a close up of these guys," said company owner Gary Klebs.

Anchorage police say they're not surprised to hear how many times the business has been targeted, given the increasing price of scrap copper.

"The problem is getting worse," said APD Detective Sgt. Doug Pickerel. "The thieves are getting more brazen. They're going after larger amounts in different areas."
