British man in bid to 'kill Trump'

A 19-year-old British man has been charged for trying to grab a police officer's gun at a Donald Trump rally in Las Vegas in an apparent bid to kill the presumptive Republican presidential nominee.

According to a complaint filed in federal court in Nevada, Michael Sandford tried to disarm the officer at Saturday's rally at the Mystere Theatre in the Treasure Island Casino before being overpowered.

It said the young man told a Secret Service agent after his arrest that he had driven from California to Las Vegas "to kill Trump," and had been to a range a day earlier to learn to shoot as he had never fired a gun before.

"Sandford acknowledged that he would likely only be able to fire one to two rounds and stated he was convinced he would be killed by law enforcement during his attempt on Trump's life," the complaint said.

It added that Sandford told investigators he had purchased tickets for a rally in Phoenix, where he "would try again to kill Trump" in the event his plan in Las Vegas failed.

Video of his arrest carried by US media show a skinny man with short brown hair and a grey T-shirt being quickly escorted out of the rally by police officers with his hands behind his back.

The prosecutor's office said Sandford was ordered held without bond, as he was considered dangerous and represented a flight risk.

Britain's Foreign Office is "providing assistance" in the case, a spokesman said.

The complaint said Sandford had told investigators he had been in the United States for about 18 months, and had lived in Hoboken, New Jersey, before traveling to California.

Sandford told investigators that he had targeted officer Ameel Jacob's gun because it was in an unlocked position and would be the easiest way to gain access to a weapon at the rally where those attending had to go through metal detectors.

He struck up a conversation with Jacob, telling him he wanted an autograph from Trump before lunging at his gun and grabbing the firearm with both hands, prosecutors said.

Sandford allegedly told the Secret Service that he had been plotting to kill Trump for about a year and finally decided to act on Saturday, as "he finally felt confident to do it."

"Sandford further stated that if he were on the street tomorrow, he would try this again," according to the complaint.

His arrest comes amid one of the nastiest US presidential campaigns in recent history, dominated by violent rhetoric, with Trump lashing out at Mexicans, Muslims and other groups.

The real estate billionaire enjoys Secret Service protection but also has his own private security detail, which has been accused of using unnecessary force to remove people from events.

A number of protesters have been arrested at his rallies where riot police are deployed in force, and there have been mounting demonstrations during his campaign appearances in recent months.

According to an investigation by the Politico news website, the security team that patrols Trump's rallies has "at times inflamed the already high tensions around his divisive campaign, rather than defusing them."

Trump's critics have also accused his campaign of racial profiling and removing people from events based on their appearance.

Sandford is due to appear in court for a preliminary hearing on July 5. He faces more than 10 years in prison and a $250,000 fine if found guilty on the charge of "act of violence on restricted grounds."

A Trump campaign official declined to comment on Sandford's arrest.
