An arrest warrant has been obtained in connection with a shooting incident Friday night on Constitution Avenue near the White House, police said.

A U.S. Park Police spokesman said Sunday that officers were seeking Oscar Ramiro Ortega, 21, on a charge of carrying a dangerous weapon.

Officers had said earlier that they thought Ortega might have information about the incident. No address was given for him.

After the sounds of shots were reported on Constitution Avenue on Friday night, an abandoned automobile was found near 23rd Street and Constitution. Sgt. David Schlosser, the Park Police spokesman, said material found in the car, including a semiautomatic rifle and a shell casing, led police to obtain the warrant. A witness also reportedly saw a man running toward the Roosevelt Bridge, police said.

It was too soon to discuss a motive or target in the incident, Schlosser said. “We won’t go into the direction” in which the shots were fired, Schlosser said. There were no reports of injury or damage.

The spot where the shots were reported, between the Ellipse and the Washington Monument grounds, is about a half-mile south of the White House. The south portico of the White House is visible from that area.

The president and first lady were not home at the time.
