Dev Hynes, the Blood Orange front man, has accused security guards at Lollapalooza of assaulting him and his girlfriend, Samantha Urbani on Friday.
Hynes took to Twitter to reveal the assault, writing, "I was jumped by three security guards and Samantha was touched by security. We are hurt. We played your festival."
Urbani also took to social media and tweeted, "How insanely ironic that I wore a homemade 'STOP POLICE BRUTALITY' shirt onstage 2day &begged audience 2take care of eachother &film arrests."
In a series of several more tweets, Pitchfork reports, Hynes outlined the attack, which came after he stood onstage and talked about police brutality.
Hynes wrote that his girlfriend was grabbed while he was thrown to the ground and that one of the security guards now claims he attacked them.
He indicated that he planned to press charges, but Urbani tweeted that they were told by those who worked for Lollapalooza that the security guards who assaulted them were privately hired.
Lollapalooza released a statement noting that they have been talking with both sides and have contacted authorities in an effort "to resolve the situation. As always, our top priority is to ensure the safety of everyone at the festival."
