DETROIT – Theives struck overnight on Detroit's east side in a daring smash-and-grab.
The men smashed their way through cinderblock to enter the back of "Tropical Paradise" store on Gratiot near Warren, but they weren't done.
From that shop, the men then smashed into "UN Beauty Supply." That was the real target.
Jaw-dropping security camera footage shows the wall behind the register vibrating. What you can't see, are the men on the other side hitting the wall with the hammer.
Then, the wall can be seen coming down, the men spilling into the store and then they can be seen going on a wild stealing spree.
What do they want to steal from a beauty supply store?
Human hair.
The packages retail for $100. The men stole so many packages, the building owner says today's total losses are $30,000.
The crime is getting old for building owner Steve Shin.
Shin came to Detroit years ago from South Korea and has worked to buy eight properties and lease them out to beauty supply stores, hair salons and tax preparation businesses.
He works to make sure he's buildings are something the neighbors can be proud of and they're well secured.
Still, his building that houses UN Beauty Supply was broken in to Jan. 1.
Thieves returned at 11 p.m. Sunday, taking their time to break through two walls to get in. That set off the burglar alarm and the shop owner called police. The men got away.
At 2:30 a.m., the men returned and continued stealing packages of human hair.
"I want to leave out of this country, leave out of Detroit I am so depressed," Shin said.
He's worried that his building and it's tenants are now targets. Next time, they may not smash their way in after hours, they may come in with a gun to steal the hair.
Last March, a beauty supply shop owner in Dearborn was shot and killed during a human hair robbery. Police later caught the gunman and he is serving prison time.
Shin says the targeting of human hair has grown out of control.
He also says he pays $40,000 in property taxes to the city of Detroit and today he's demanding better police protection and response time.
