The Ray-Ban x Boiler Room Weekender festival at Split Rock Resort in Lake Harmony, Pennsylvania was shut down early this morning, Thump reports. “We don’t have the exact details of what transpired, but for the safety of all our artists and guests we had to shutdown,” a spokesperson for Boiler Room said in a statement. Multiple witnesses saw police handcuffing and arresting people at the festival, and venue staff reportedly confiscated phones from concertgoers filming the arrests. Several artists who were scheduled to perform have addressed the events on Twitter:

Grabbed at, threatened and hit for filming these monsters handcuffing and parading a young black girl having a panic attack- playing with her life! She was shaking in the center lobby as everyone watched helplessly- this monster was only held back from attacking me by a young security guard that I had chatted up the night before FUCK THIS POLICE STATE YOU HAVE NO RIGHT @rayban #ittakescourage
