Last month (Apr15), Fekete revealed he is suffering from a rare form of cancer, and told fans he had undergone "major surgery" to remove a large tumour from his abdomen.

He was told by doctors the cancer had spread to his lungs and spine and Fekete is beginning chemotherapy in the near future in a bid to beat the disease, but he is also seeking "an alternative treatment plan", because his cancer is so rare and little research has been done.

Fekete launched a crowdfunding site to raise at least $76,000 (£47,500) for treatment costs, and in just 12 days, he surpassed the goal.

His bandmates have been on the road without him, and as they visit each city, the rockers have been collecting funds for Fekete with the merchandise they sell each night.

However, after playing at Chicago, Illinois' Lincoln Hall on Friday night (22May15), they were shocked to see their tour van was broken into. Not only did the thieves get away with "thousands of dollars in personal items and show settlements," they also stole "all cash donations we collected for Thomas over the last 8 shows at our merch table".

The band wrote in a Facebook.com post, "This last detail is perhaps the most heartbreaking of all in that so much positivity and amazing generosity could be ruined by one bad person(s)."

Surfer Blood also called on fans to keep a lookout in Chicago-area pawn shops for the missing belongings, including one-of-a-kind guitar pedals.

As none of their instruments were stolen, their U.S. tour is going on as scheduled.
