Republican Presidential candidate, Donald Trumph’s campaign on Friday was called off due to fears between supporters and demonstrators. He called the protesters as “dangerous people.”

The arena of University of Illinois was surrounded by hundred of protestors at Chicago hours before Trump arrived. The protesters clashed with the police. Police have arrested at least six people.

Supporters of the GOP frontrunner shouted out “We want Trump” and non-supporters yelled “F*ck Donald Trump.” An African-American woman was racially insulted during the protest.

“If he can’t even handle Chicago, what makes him think he could handle Isis?” Violet Ornelas, one of the protesters said to The Guardian. Protesters opposed the  Republican candidate on the basis of  immigration policy, race and other issues.

“Mr. Trump just arrived in Chicago, and after meeting with law enforcement, has determined that for the safety of all of the tens of thousands of people that have gathered in and around the arena, tonight’s rally will be postponed to another date,” the Trump campaign said in a statement. “Thank you very much for your attendance and please go in peace,”  CNN reports.

25-year-old community organizer, Maria Hernandez, started dancing as soon as a Trump campaign staffer announced that the rally had been postponed. “I’ve never been more proud of my city,” Hernandez exclaimed.

“Some of these protesters are very dangerous people. You can’t even have a rally in this country anymore without violence,” the real estate businessman said to Daily Mail. “I think a lot of people think that it was wrong that we were stopped.”

This is not the first incidence of Violence during a Trump rally. Last week, criminal charges were levied on a protester for an attack on a non-violent protester.

Marco Rubio, the  senator of Florida told the Fox News there was “an industry” of  protesters  in Chicago with a few of the participants “probably being paid to do this.”
