CHICAGO (AP) — Three thieves battered through a wall, crawled close to the floor to dodge motion detectors and stole six duffel bags filled with human hair extensions from a Chicago beauty supply store.

The Chicago Tribune reported Saturday that the hair extensions were worth $230,000.

Store owner Don Shin says the criminals took his best merchandise. He thinks the culprits will try to sell the extensions on the street or to salons. The thieves broke through a wall from an attached empty storefront at about 2 a.m. Saturday.

Extensions can be made from artificial or human hair. They are used in salons to add length and volume to a hairstyle.

Shin says the thieves didn’t take any of “the cheap stuff” and “knew what they were doing.”
