The Secret Service arrested a 41-year-old Iowa man one block from the White House today after a search of his car uncovered a rifle and ammunition, law enforcement officials confirmed to ABC News.

The man, R.J. Kapheim, from Davenport, Iowa, approached a uniform division officer on the corner of 15th Street and E Street NW at 12:54 p.m. and “stated that someone in Iowa told him to go to the White House,” said Secret Service spokeswoman Nicole Mainor.

Kapheim was not threatening in any way, but his behavior was deemed suspicious, she said.

Officers located and conducted a search of his vehicle, a 2013 Volkswagen Passat with Iowa tags. It was parked on Constitution Ave between 16th Street NW and 15th Street NW.

The weapon, a .30-30 rifle, and ammunition -- about 40 rounds -- were found in the car, along with a 6-inch blade, officials said.

He is being held on charges of possessing an unregistered firearm, among others that are forthcoming, Mainor added.

There have been several incidents over the past few months of people breaching security and jumping the White House fence.
