Story highlights Bryan Moles, 43, of Edinboro, Pennsylvania, was arrested at the Trump International Hotel

The police report said Moles was in possession of two guns and 90 rounds of ammunition

Washington (CNN) A man with an AR-15 assault rifle, a 40-caliber handgun and 90 rounds of ammunition was arrested at President Donald Trump's namesake hotel in Washington early Wednesday morning after a tipster warned police, authorities said.

Bryan Moles, 43, of Edinboro, Pennsylvania, was charged with carrying a pistol without a license and possession of unregistered ammunition, police said.

According to a police report, officers observed a firearm in "plain view" inside his car, which led to a search of the vehicle and a second weapon and ammunition found in the glove box.

"I believe that the officers and our federal partners and, in particular, the tipster coming forward averted a potential disaster," Metropolitan Police Department Chief Peter Newsham said at a Wednesday news conference.

A law enforcement official told CNN that the individual who alerted authorities in Pennsylvania said that Moles was traveling to DC and wanted to kill the President. CNN is unable to corroborate Moles' intentions. People in the area said they have repeatedly heard Moles firing his gun on his property.
