A man scaled the White House fence Tuesday evening and got onto the grounds, but was quickly taken into custody by the Secret Service.

A Secret Service spokesman said the man was carrying a backpack, which officials were examining Tuesday night.

He scaled the fence in front of the White House north lawn about 7:45 p.m. and was spotted by the Secret Service, the spokesman said.

Television footage showed two uniformed officers of the Secret Service placing the man in custody about 7:45 p.m.

He lay prone on the lawn, while one officer bent over him and another stood next to him.

They were within 10 or 15 feet of the tall iron picket fence.

It was not immediately clear who the man was or why he climbed the fence.

The last event on the president’s formal schedule was set for 4:30 p.m.
