A man in illegal possession of a shotgun and a loaded handgun was arrested at an intersection near Donald Trump’s rally in Coachella, California, on Saturday, police said.
The 49-year-old suspect, Vem Miller, was driving a black SUV when he was stopped at a security checkpoint by deputies, who located the two firearms and a “high-capacity magazine”.
Mr Miller was then taken into custody “without incident”, the Riverside County Sheriff’s office said, and booked on possession of a loaded firearm and possession of a high-capacity magazine.
The US Secret Service said Trump “was not in any danger”, adding that the incident did not impact protective operations.
A local sheriff called the suspect a “lunatic” and his office added the encounter did not affect the safety of Trump or the rally’s attendees.
Many questions remain unanswered.
While Riverside County Sheriff Chad Bianco said it was impossible to speculate about what was in the mind of the suspect, whom he called a “lunatic,” he said he “truly believed” that his officers had prevented a third assassination attempt.
He added that it might be impossible to prove that this was the man’s intent.
A federal law enforcement official told CBS News there was no indication of an assassination attempt connected to this incident.
Federal authorities say they are still investigating the incident, and it would be up to them to pursue any additional charges.
Mr Bianco is an elected official and a Republican who has previously expressed support for Trump. He is also acting as a surrogate for Trump’s re-election campaign.
The incident – which occurred at 16:59 PDT (00:59 GMT) – an hour before Trump was scheduled to appear on stage – highlights, once again, the intense security operation around him, and the dangers facing the former president, with just over three weeks to go until the election.
It follows two high-profile alleged assassination attempts on Trump earlier this year.
Mr Miller was was charged with two misdemeanour weapons charges and was released on a $5,000 (£3,826) bail. No federal charges have been filed. (BBC)
