weaves *Chicago’s black market weave business just got an influx of inventory.

Police are looking for nine people involved in a mass hair extension heist at a beauty supply store in Oak Lawn, Illinois, just outside of Chicago. The store manager says hooded thieves stole over $50,000 in weaves, but left the cash register untouched.

“What they do is, one starts to throw a landscaping brick through the front window, so as that breaks the window, you see the group all goes in a one time, then they all run out,” said Cmdr. Randy Palmer, Oak Lawn Police Dept.

“It’s crazy, it’s unbelievable the way it happened,” said Al Salman, beauty supply manager.

A camera inside facing the door caught the suspects entering one by one, nine burglars in all wearing hoodies, some even gloves. The manager says they swiped at least $50,000 worth of merchandise.

It was planned to the point that one thief empties a box to get after high-end extensions made out of human hair worth $100 to $300 per package.

“They did it right. They knew what to get, they exactly got the expensive stuff. You’re talking about tens of thousands of dollars gone in less than a minute,” said Salman.

And it was only hair extensions, an overhead camera shows the cash register untouched.

The store manager said they’ve installed a metal grate on the door now. Oak Lawn police say they’re looking closely at the surveillance video, but so far, no one is in custody.
