A burglar has allegedly danced away with several items belonging to Mark Ballas and Derek Hough.

The band Almost Amy -- which consists of the two Dancing with the Stars professionals, singer Emily Grace, drummer Harry Sullivan and bassist Sam Marder -- say their van was burglarized on Saturday morning while parked outside a Minneapolis restaurant.

"Our van was broken into in Minneapolis!!" reads a Saturday posting on the band's MySpace blog.

"Almost Amy flew into Minnesota this morning for some upcoming shows at Cancer Charities over the next week. We had a 2 hour drive ahead of us, so we decided to stop for lunch before the drive at Outback Steakhouse in Minneapolis. While inside eating our band van was broken into and they took all of our personal items... Everything from Passports and Visas, wallets, ID's, laptops, ipods, cell phones, Emilys purse, cameras etc... We are offering a $5000.00 reward for information leading to the return of our stuff... NO QUESTIONS ASKED!!! We just want our personal items back."

Kristi Yamaguchi -- who claimed Dancing with the Stars sixth-season mirror ball trophy with Ballas this past spring -- was also with the band when the alleged incident occurred. 

"I feel so bad," Yamaguchi told Minneapolis-St. Paul ABC affiliate KSTP-TV. "These guys came in for a good cause to help out and it's not starting out so good."

Despite the monetary value of some of the missing items, Yamaguchi added that wasn't what stung the most.

"It's more emotional because there are so many memories," she told KSTP-TV.

As of early Monday morning, the band's burglarized items had yet to be recovered.

"It has been a really tough few days for all of us," reads a posting on Almost Amy's website.  "But the outpouring of love and support from you guys has been incredible!! We want you to know how much we truly appreciate your kindness. Still no news, but we are still offering a $5000 REWARD for any information that leads to the return of our stolen items."
