Joseph Caputo, wearing an American flag and carrying a binder, jumped over the fence of White House on Thursday before immediately being caught and taken into custody, the US Secret Service said.
Futher details about the man were not given.
ABC News and other media sources reported that The White House was locked down and close streets were blocked at the time of the incident. Several security personnel also patrolled along the streets to control the area.
Victoria Pena of Houston, a witness to the incident said, "I just heard him take a big, deep breath and whisper to himself, 'All right, let's do this' and he took off," Pena said. "It was chaotic. Everyone around us was yelling and kids were crying. It was pretty unexpected."
Security and guard dogs raced toward the man and he stretched out waiting for them, Pena added.
At least three people have attempted to jump the White House fence this year and the Secret Service has tightened security by adding spikes to the top of the fence.
A woman was detained in July and another person was detained in April in similar incidents.
