WASHINGTON — The U.S. Capitol and Capitol Visitor Center were placed on lockdown briefly Friday morning, but the shelter in place order has since ended.

Capitol Hill police said they were investigating a “person of interest.” No further details were available as of Friday morning.

The Senate sergeant at arms initially issued a lockdown alert for the building and visitor center, saying police activity has been reported. Capitol office buildings are open.

House press gallery staff said the building is on lockdown but that the House met briefly and immediately recessed.
