A gunman who fired at a White House checkpoint ?was shot by officers and died after being taken to the hospital on Saturday evening, the Secret Service said.

The man approached the checkpoint at 17th Street and Pennsylvania Avenue near the White House, pulled a gun out of his bag, and started shooting at officers, according to a Secret Service statement sent to Reuters.

Officers returned fire and shot the suspect, the agency said.

A bystander was struck by gunfire, the statement said, but it did not make clear how badly the person was hurt. Another Secret Service statement, cited by multiple news outlets, said it was not clear whether the bystander was hit when ?the gunman began shooting or during the subsequent exchange of gunfire.

The shooting suspect was identified as an emotionally disturbed person, a law enforcement official told Reuters, adding that a “stay-away order” had been issued to him previously.
