A man jumped a security barrier and rushed the stage at Donald J. Trump’s rally in Dayton, Ohio, recently, leading to a brief moment of panic when Secret Service briefly surrounded the candidate. The night before, Trump abruptly cancelled his rally in Chicago as hundreds of activists scuffled with his supporters inside the arena where it was to take place. But the Dayton event was relatively quiet, by Trump’s standards, until the end.

One man began protesting about 10 minutes before Trump finished talking. “What took him so long to put up his hand, we’re almost finished!” Trump said, mocking the man and telling him to “go back to mommy.” Not long after that person was escorted out, a man jumped over a security barrier and rushed towards the stage, a moment captured on a video quickly posted to YouTube.

People could be heard screaming, and Trump ducked his head, grabbing his podium with both hands. One of Trump’s personal security guards was the first to jump on stage. Three other men who appeared to be Secret Service agents jumped on stage, and all formed a ring around Trump for a few moments.

In an e-mail, a spokeswoman for Trump, Hope Hicks, said, “A man attempted to breach the secure buffer and was removed rapidly and professionally.” According to the Secret Service, the man was arrested by the Dayton Police Department.
