Republican presidential nominee Donald Trump was rushed off stage by Secret Service agents during a campaign rally in Reno, Nevada, Saturday evening after a disturbance broke out in the crowd.

Two Secret Service agents quickly surrounded Trump, then hustled him off stage.

The nature of the disturbance was unclear. But several security officials escorted a man out of the venue soon afterward.

Several minutes after the incident, Trump reappeared and finished his speech.

"Nobody said it was going to be easy for us, but we will never be stopped. I wanna thank the Secret Service. They don't get enough credit. They're amazing," Trump said, according to Politico.

Trump's campaign released the following statement following the incident:

I would like to thank the United States Secret Service and the law enforcement resources in Reno and the state of Nevada for their fast and professional response. I also want to thank the many thousands of people present for their unwavering and unbelievable support. Nothing will stop us - we will make America great again!

According to sources who spoke with ABC News, the crowd began to panic after a man shouted "gun" when another crowd-goer attempted to raise a sign. However, no gun was found.

To note, everyone — including the media — goes through metal detectors and is subject to thorough searches by the Secret Service at events where they are protecting a person or people. And even if a gun had gotten through their security procedures, it is unlikely the Secret Service would have allowed Trump back on stage.

The man detained by police has since been released, according to a reporter with KRNV-TV.
