Australian electronic band Rüfüs Du Sol responded to assault that occurred during their sold-out Los Angeles concert at Rose Bowl with 90,000 fans in attendance.

"This type of behavior is completely unacceptable anywhere, and the fact that this happened at one of our shows was devastating to learn about," the group said

The incident occurred at the Australian trio's Aug. 16 show in Pasadena, Calif., an event some fans say suffered from overcrowding.
