Hot 97’s Summer Jam 2015 ended in chaos on Sunday night in East Rutherford, New Jersey.

New Jersey State Police wearing riot gear stood outside MetLife Stadium as some people who did not have tickets tried to get into the venue. According to officials, police later used tear gas to try to disperse the crowd.

State police said a crowd tried to “illegally” force its way into the show, but the gates — guarded by police — were closed and blocked off. According to reports and videos, photos and testimonies posted on social media, non-ticket holders climbed fences, threw bottles at the police and broke through security barriers to make it into Summer Jam.

The concert then shut the stadium’s gates and called in officers for back-up to maintain order. Reports claimed an armored state police vehicle sounded loud noises and police deployed tear gas. A state police spokesperson confirmed that multiple arrests were made, but the specific number of arrests was not yet released.

Due to the uproar, some attendees who had bought tickets weren’t let into Summer Jam. Hot 97 released a statement after the event, noting that fans whose tickets were not scanned will receive refunds:

Ebro, who hosts Ebro in the Morning on the radio station, commented on the event during his show on Monday morning and blamed “a few idiots” for the dispute between crowds and state police. “You cannot throw bottles at police,” Laura Stylez, co-host of the Ebro in the Morning show, said. “What is wrong with you?”

“The people that made it go sideways, you’re an idiot,” Ebro said. “Throwing bottles at the state troopers, we don’t like that. You’re trying to ruin it for everybody. Shame on you.”

The concert lineup included artists like Kendrick Lamar, Trey Songz, Big Sean, Meek Mill and Ty Dolla $ign. Watch Ebro discuss the situation below.
