A man has died after lighting himself on fire outside the White House at approximately 12:20 p.m. Wednesday. According to a tweet posted by U.S. Secret Service, the man lit himself on fire near 15th and Constitution Ave on national park grounds.

Witness video footage shows a moving figure completely ablaze moving across the Ellipse. U.S. Park Police identified the man as Bethesda, Maryland resident Arnav Gupta, 33. Following the incident, authorities took Gupta to the hospital where his condition was said to be “life threatening.” Authorities announced that Gupta ultimately succumbed to his wounds early Thursday.
