According to his Twitter, Dev Hynes and girlfriend Samantha Urbani were assaulted by security guards following their set at Lollapalooza. The Blood Orange singer and Urbani had worn homemade shirts on stage with the names of victims of police brutality written on them and talked about the issue during their set. The festival has not made an official statement about the incident, though Urbani says she was told that the guards were private hires and not Lollapalooza staff. Read tweets from both of them that describe the event in detail below.

Samantha & I made this T-shirt which I'm wearing today. The set is dedicated to these names & more. We remember. pic.twitter.com/si4ndgDrK1

Terrifying thinking about if Dev was attacked like that & had a physical disability- like a heart problem, or ASTHMA #RIPEricGarner

How insanely ironic that I wore a homemade "STOP POLICE BRUTALITY" shirt onstage 2day &begged audience 2take care of eachother &film arrests

— samantha urbani (@SamandudeBITCH) August 2, 2014

Apparently people are tweeting & writing on @lollapalooza Facebook page and they keep deleting the comments

— Devonté Hynes (@devhynes) August 2, 2014

If they're doing this to the musicians playing, then how have they been treating all the attendees throughout the day?

— Devonté Hynes (@devhynes) August 2, 2014

Rly not trying 2be 2self victimizing btw- this has shaken me so deeply bc this shit happens 2 ppl on all levels, constantly- feels endless

— samantha urbani (@SamandudeBITCH) August 2, 2014

BTW after talking w lollapalooza ppl we've discovered the guards who assaulted us were NOT lolla staff, but privately hired for that stage.

Thanks for the support. We are both very shaken and I am pretty bruised up. But blessed to be alive in this world. Others aren't as lucky. X

— Devonté Hynes (@devhynes) August 2, 2014

Ps. One of the security guards is claiming that I assaulted him which is insanity. If you saw the incident please get in touch. Thanks.
