Trump rushed off stage during campaign over gun shot fears

Secret Service agents rushed US presidential hopeful Donald Trump offstage on Saturday evening during a rally in Nevada after they determined a protester in the audience might pose a threat to the Republican presidential candidate.

'Go! Go!' agents shouted as they whisked Trump away and a combination of local police and private security wrestled Austyn Crites, 33, to the ground in the front of the crowd.

Mr Crites identifies as a Republican who supports Democratic presidential candidate Hillary Clinton, according to his Facebook page.

A Trump campaign official told Daily Mail that the suspect, whom rally-goers already identified as an anti-Trump protester, caused a panic when he reached into his waistband.

At that point, the campaign official said, a voice called out: 'He's got a gun!'

Trump's protective detail sprang into action, pulling him offstage as a sea of bodies scattered, screams rang out and authorities dragged Mr. Crites away as he kicked and strained.

U.S. Secret Service said in a statement that 'a commotion' had occurred 'in the crowd immediately in front of the stage' and 'an unidentified individual shouted, "gun".'

"Secret Service agents and police officers immediately apprehended the subject. Upon a thorough search of the subject and the surrounding area, no weapon was found," the statement added.

The man has been cleared and released.
