The Secret Service said Saturday afternoon that it was responding to reports of a man who "allegedly suffered a self-inflicted gunshot wound" along the White House's north lawn fence.

The security agency said that medical personnel had been called to respond to the male victim, but he was declared dead at the scene.

"The subject approached the vicinity of the North White House fence line and removed a concealed handgun and fired several rounds, none of which appear at this time to have been directed towards the White House," the Secret Service said in a statement.

The agency said they had identified the shooter but were withholding his name until they could notify next of kin. The Metropolitan Police Department will lead an investigation into the shooting with the support of the Secret Service.

The agency alerted the public to the incident following reports of a lock down at the White House. They added that there were no other reported injuries relating to the incident.

As they responded to reports of a gunshot near the north lawn, the Secret Service told those in the White House to shelter in place. As they investigated the incident, agents could be seen sprinting across the north lawn and the executive driveway with their guns drawn.
