Donald Trump postponed his Chicago rally for safety concerns after thousands of protesters and supporters gathered inside the University of Illinois-Chicago Pavilion Friday.
"Mr. Trump just arrived in Chicago and after meeting with law enforcement that for the safety of tens of thousands of people that have gathered in and around the arena, tonight's rally will be postponed until another date," an announcer said. "Thank you very much for your attendance and please go in peace."
The crowd erupted in shouts and cheering and some scuffles broke out in the minutes after the announcement.
Shortly after, Trump spoke with MSNBC saying he met with law enforcement for about a half hour before the event.
“I think it was the right thing to do under the circumstances," he said. However, CPD said in a statement after the interview the department had not advised Trump's campaign to cancel the rally and did not issue any public safety threats or safety risks.
Trump also noted there was a high demand for people to attend the rally.
“We’ve had by far the biggest rallies. We had over 25,000 people wanting to come today," he said. "We have had very little protest and we’ve had nobody hurt."
He also addressed concerns surrounding protesters at the event.
"You can’t even have a rally in a major city in this country anymore without violence, or the potential of violence. That’s why we called it off," he said. "My decision is: I just don’t want to see people hurt… We can come back and do it another time."
The Republican presidential front-runner was scheduled to speak at the arena at 6 p.m., with doors opening at 3 p.m. The first person in line to wait for a spot at the free event arrived at 3 a.m. The arena seats 9,500.
Chicago Police said Friday night five people were arrested amid the chaos that erupted following the announcement. Additionally, two CPD officers were wounded – both with non life-threatening injuries.

In the latest Republican debate Thursday, Trump refused to "stoop to being politically correct" and avoid making statements such as "Islam hates the West." He also delcared that he would "not touch Social Security" and would "leave it the way it is."
Last month, Trump went after the Ricketts family, who own the Chicago Cubs, in a tweet accusing the family of donating money to campaigns to prevent him from winning the Republican nomination.
“I hear the Rickets [sic] family, who own the Chicago Cubs, are secretly spending [money] against me,” Trump tweeted. “They better be careful, they have a lot to hide!”
Marlene Ricketts, the family’s matriarch, donated $3 million to Our Principles Political Action Committee last month.
