A U.S. Park Police crime bulletin issued before Ortega's arrest said he is known to have mental health issues, adding "Ortega should be considered unstable with violent tendencies."

Authorities are investigating his mental health and say there are indications he believed his attack on the White House was part of a personal mission from God, according to a law enforcement official. There are also indications the man had become obsessed with Obama and theWhite House, according to two officials, who spoke on the condition of anonymity because the investigation is ongoing.
Authorities said the bullets discovered Tuesday by the Secret Service have not been conclusively connected with the reports of gunfire near theWhite House on Friday night. On Friday, authorities found an abandoned vehicle with an assault rifle inside.
Ortega, 21, was arrested Wednesday afternoon at a hotel near Indiana, Pa., some 55 miles east of Pittsburgh, the Secret Service said. He was in Pennsylvania State Police custody. A tip from someone who saw and identified Ortega led to his arrest, Secret Service spokesman George Ogilvie said.
Ortega did not resist arrest, said Pennsylvania State Trooper Lt. Brad Shields. State troopers said Ortega had visited the hotel in recent days, and investigators believed he was back in the area Wednesday. The Secret Service passed out photographs, and a desk clerk recognized his picture and stalled him while notifying police.
Ortega's first court appearance is scheduled Thursday afternoon in Pittsburgh, according to the staff of U.S. Magistrate Judge Cynthia Reed Eddy.
