A man was arrested on Tuesday for having a firearm inside his car while attending an event at the Trump International Hotel in Washington D.C., police said.

The suspect had entered the hotel and approached a security checkpoint that was manned by Secret Service agents, according a D.C. police spokesman.

The man did not make any threats but he “self-reported having a firearm in his vehicle” when questioned at the checkpoint.

Police discovered the gun along with ammunition in his vehicle.

The man was arrested on charges of possessing an unregistered firearm and unregistered ammunition. His name was not released on Tuesday.
