New Jersey State Police clashed with unruly concertgoers outside of the 2015 Hot 97 Summer Jam concert, which took place at MetLife Stadium in East Rutherford, N.J., on Sunday night (June 7). Mobs of people were upset that they couldn’t get inside the venue even though some had tickets.

According to WABC-TV New York, police in riot gear blocked the gates and ordered people to leave the area after a few men and women tried to rush the gates. When they refused, authorities used piercing loud noises and tear gas to disperse the crowd.

State police said crowds of people were trying to illegally force their way into the sold out concert, which featured Kendrick Lamar, Chris Brown, Fabolous, Meek Mill and others. Police say they witnessed people climbing over the gates and forcing their way in through MetLife’s own security detail. Troopers were eventually called in to restore control of the situation.

On social media, videos featured police arresting people and pepper spraying the crowd. Glass bottles and other items were also thrown at officers. As of press time, the total number of arrests is not known.

Ebro, the host of Ebro in the Morning on Hot 97, blamed "a few idiots" for the disruption outside of the Summer Jam concert. He said the station will not tolerate bad behavior regardless if people had tickets or not.

"The people that made it go sideways, you're an idiot," he told "Throwing bottles at the state troopers, we don't like that."

"You're trying to ruin it for everybody," he added. "Shame on you."

Despite the unrest outside of the venue, the concert went on as scheduled inside with concertgoers enjoying the performances.

"Everything was so positive inside, it's unfortunate this happened outside," Ebro said.

Reps at Hot 97 also announced that people who purchased an unscanned Summer Jam ticket and couldn't get inside the venue are able to receive a refund at point of purchase.
