(PITTSBURGH) -- A man who federal authorities suspect was involved in a shooting near the White House on Friday has been captured at a Pennsylvania hotel less than 24 hours after the U.S. Secret Service confirmed that bullets presumed, but not yet confirmed, to be from the same shooting were discovered on White House grounds.

Authorities were concerned that the man could pose a threat to President Obama. The Secret Service suspects that bullets fired in the incident may have hit the White House after one round was found Tuesday in a window and another in the building's exterior. The rounds have not yet been conclusively linked to the incident.
Police believe that the suspect, Oscar Ramiro Ortega, of Idaho, is mentally ill. Ortega has an extensive record, ranging from domestic violence to drug charges. Sources say a police investigation uncovered evidence suggesting that Ortega has a fixation on the White House and may have spent time at the recent Occupy D.C. protest.
At 9:30 p.m. Friday, police received reports of shots fired in the bustling area of 16th Street and Constitution Avenue. Authorities would later find a car abandoned in the area. The suspect had fled, but what police discovered inside the vehicle left them deeply concerned: an assault-style rifle and empty shell casings.
Police linked the car to Ortega and were hunting him ever since.
It was not immediately clear whether Ortega would have been capable of launching a sophisticated attack, but police were still fearful of what he might do next.
President Obama, who is currently on a visit to Australia, was not present at the White House at the time of the incident, and has been out of town for the past week.
