Police are searching for a 21-year-old Idaho man who shot at a White House window with an AK-47 assault rifle on Friday.

Police have named 21-year-old Oscar Ortega Hernandez of Idaho as a suspect in the bizarre shooting. Witnesses tell police they heard shots and saw two speeding vehicles leave the area. An AK-47 rifle was recovered nearby.

The Secret Service found one bullet lodged in the protective ballistic glass of a historic exterior window. Another spent round was found on the grounds of the White House.

U.S. President Barack Obama was not in his official residence at the time of the shooting. He landed in Australia yesterday amid heightened security after documents were found revealing his possible locations while in Australia.

According to the Daily Mail, the documents detailing the Secret Service’s scouting locations for possible Obama visits were left in a van in full view of passersby.

The Secret Service has tightened security to ensure the safety of the president.

UPDATE I:
According to published reports, the U.S. Secret Service said Pennsylvania authorities arrested Oscar Ramiro Ortega-Hernandez this afternoon at a Pennsylvania hotel. Ortega-Hernandez was taken into custody without incident.
