Police in Wichita, Kansas are trying to figure out who stole a set of costumes from the Blue Man Group this week.

Wichita police said between Tuesday night and Wednesday morning, the unknown suspect gained access to the area where the group’s costumes were being stored at the Century II Convention Center.

Several outfits valued at more than $1,000 were taken.

A photo released by the Wichita Police Department on social media showed a man walking in what appears to be a hallway, carrying a laundry basket containing items taken during the theft.

The Blue Man Group was in Wichita for two nights of shows.

A spokesperson for the Blue Man Group said the theft did not affect the performance.
