US rapper threatens Donald Trump while toting stolen gun

A US rapper brandishing stolen guns and threatening Donald Trump in a viral video has been arrested after a firearm salesman recognised the missing weapons.

Star of reality show Sons of Guns Joe Meaux immediately spotted the custom-made guns when he clicked on a link titled "Rapper Threatens Trump".

"As I’m watching it, I’m thinking these guns are very recognisable. As I watched more, I realized that they were very familiar. They were stolen from me last year," he told Fox News yesterday.

When the gun salesman called authorities he was informed police and the Secret Service were already aware of the social media post made by Demarcus Davis, 22.

Going by the name Maine Musik, the rapper posted the video to Instagram saying he wanted to "go to war with Donald Trump because Donald Trump is tryin’ to take food stamps from my momma and that’s all… she got".

"Let Donald Trump know it’s up over here. We want war; we’re going to declare war," he said.

"F--- Donald Trump."

Davis was arrested earlier this month and is facing drug and gun possession charges.
