August 5, 2021: -On Tuesday, a Pentagon police officer died after getting stabbed many times in the neck outside the Pentagon, officials familiar with the incident told NBC News.

According to NBC News, the officer opened fire on the assailant after the attack began outside the Pentagon metro entrance. The assailant was shot dead by police, but it was unclear which officer killed the assailant.

“I’m saddened to know about the passing of a Pentagon police officer,” Sen. Mark Warner, a Virginia Democrat, tweeted on Tuesday.

“My heart goes out to the officer’s family and friends and the entire Pentagon Police force,” said Warner, the Senate Intelligence Committee chairperson.

The Pentagon was placed on lockdown after several gunshots were fired at the building, but it reopened after over an hour.

The exact details and sequence of events remain murky. Woodrow Kusse, the police chief of the Pentagon Force Protection Agency, said that “few injuries resulted from the incident” but did not confirm the officer’s death.

Although, the Fairfax County Police Department expressed condolences for the death of a police officer of the Pentagon.

Kusse said authorities are not looking for one more suspect actively, “The incident is finished, the scene is secure, and importantly, there is no continuing threat to our community,” he added.

The FBI led an investigation into the incident, as the motivations behind it remain unknown.

“At this time, it would be premature to speculate on a motive and to protect the integrity of the investigation, and we cannot provide additional details at this time,” the FBI Washington Field Office said.

The incident occurred on a metro bus platform part of the Transit Center, only steps far from the Pentagon building in Arlington County, Virginia.

While the lockdown was uplifted, the Pentagon Force Protection Agency tweeted that the public should stay away from the metro rail entrance and bus platform area as it is “still an active crime scene.”

At the shooting, Defense Secretary Lloyd Austin and Gen. Mark Milley, chairman of the Joint Chiefs of Staff, were at the White House to meet with the U.S. President, Biden
