U.S. authorities say a 21-year-old man has been arrested in connection with shots that were fired at the White House last week.

The U.S. Secret Service, which is tasked with protecting the president and other top officials, said Wednesday that Oscar Ortega-Hernandez was detained in Pennsylvania. The agency said state officials arrested him at a hotel.

Authorities say two bullets hit the White House, including one they say broke an exterior window but was stopped by a layer of bulletproof glass.

President Barack Obama and his wife, Michelle, were not home at the time of the November 11 incident. On Friday, they were in California, before heading to Hawaii, where Mr. Obama hosted an Asia-Pacific economic summit.

Authorities began pursuing Ortega-Hernandez after linking him to an abandoned car found Friday with a weapon in it. Ortega-Hernandez is described as a Hispanic male with an arrest record in three U.S. states and several tattoos, including the word “Israel” on his neck.
