A security guard shot and wounded a man who stabbed a woman in Union Station around 1 p.m. Friday, resulting in a brief evacuation of the station, according to the Metropolitan Police Department.

MPD Director of Communications Gwendolyn Crump indicated the stabbing may have been a domestic dispute, according to CNN, although the details of the stabbing are still unconfirmed.

The shot was fired near a McDonald’s restaurant around the Amtrak terminals, according to The Washington Post.

Immediately following the gunshot, MPD tweeted that it was not an active shooter situation.
