A man who set himself on fire near the White House has died of his injuries, U.S. Park Police said Thursday.
The man, identified as Arnav Gupta of Bethesda, Maryland, set himself on fire Wednesday afternoon on the Ellipse Park, not far from the Washington Monument, in full view of passersby.
He "died of his injuries later that evening," police said in a statement.
Park Police said they had turned over their investigation to the Washington Metropolitan Police Department.
Multiple outlets reported that Gupta was the man who had been reported missing Wednesday morning by police in suburban Montgomery County, Maryland.
In a Facebook post asking for public help locating him, the police said that Gupta, 33, was last seen by his family when he left his home around 9:20 a.m. Wednesday.
Police said in the post that they "are concerned for Gupta's physical and emotional welfare."
The Secret Service said Wednesday that officers responded in "seconds" after Gupta set himself on fire, then began administering first aid and transported him to a hospital.
The White House did not immediately respond to CNBC's request for comment on Gupta's death.
Alina Berzins, 17, told CNBC on Wednesday that she was visiting the National Mall with two of her cousins and saw the man "running, and then we saw him covered in flames."
The man's motive remains unclear. Another man had set his jacket on fire outside the White House's North Fence Line in April. That man's injuries were not life-threatening.
