U.S. Capitol Police arrested an 18-year-old on Tuesday afternoon near the West Front of the Capitol after he was seen carrying a loaded shotgun. Officers challenged the individual to drop his weapon, and he complied without incident.

Authorities reported that the suspect was wearing a tactical vest and had multiple rounds of ammunition on his person. A white Mercedes SUV parked nearby contained a helmet and gas mask. Maryland Avenue between First and Third Streets Southwest was temporarily closed while police conducted their investigation.

Police stated that there is no ongoing threat and no additional suspects involved. The suspect, who does not reside in the area, was taken into custody, and authorities have not yet disclosed a motive. Officials cautioned employees and bystanders to avoid the area during the investigation.

The arrest comes amid ongoing security measures at the U.S. Capitol, where heightened vigilance has been standard following previous threats and incidents. Authorities said the swift response and controlled handling of the situation prevented any danger to Capitol staff, visitors, or lawmakers.
