Security agents have hustled presidential candidate Donald Trump off stage in Nevada following a perceived threat in the crowd.

Trump was half an hour into a  speech when an audience member shouted: “He’s got a gun” and indicated a shaven-headed man who is believed to have been disrupting the rally.

Two agents took hold of Mr Trump’s shoulders and rushed him backstage at the rally in Reno.

Other secret service agents pinned the man to the floor before manhandling him out as heavily-armed police officers flooded into the room.

TV video showed the man being escorted away by a group of police officers, with his hands behind his back.

Trump later returned to the stage and declared: “I want to thank the Secret Service, they don’t get enough credit, they are amazing people.

“We will never be stopped”.

‘Trump’ goes up in flames

He turned “You’re fired” into his reality show catch-phrase, but it was Trump who went up in flames on Saturday – or at least an effigy of him did, as part of Britain’s annual bonfire night celebrations.

An 11-metre-high model of Trump was burned at a fireworks display in the town of Edenbridge, 50km south of London.

The sculpture showed Trump, complete with his trademark mop of hair, holding his Democratic rival for the White House, Hillary Clinton, in a headlock, and sporting a pair of Mexico-themed boxer shorts.

“I think he would be quietly amused,” artist Frank Shepherd said of his muse.

Britain celebrates the failed attempt to blow up the Houses of Parliament in 1605 by letting off fireworks and lighting bonfires with an effigy of the “Gunpowder Plot” leader Guy Fawkes on top.
