Police say there was no apparent connection between a shooting at Washington's massive Union Station and the anniversary of the Sept. 11, 2001, terrorist attacks.

D.C. police Commander Jeff Brown told reporters at the station that fears were heightened Friday because of the timing but that the facility was secured without incident.

Police have said that a man stabbed a woman and then was shot by a security officer at the transit hub.

Brown says the officer was a private security guard associated with the Securities and Exchange Commission. Brown says the man "lunged" at the guard with a knife.

Brown says the guard fired one shot and the man was wounded in the side. Both the man and the woman are believed to have injuries that aren't life-threatening.

Amtrak is based at Union Station. Polly Hanson of Amtrak police says trains were briefly halted and the station was briefly evacuated. She says the station has since reopened and trains are running normally.

Police say a man stabbed a woman and he was then shot by a security guard at Washington's busy Union Station.

DC Police spokeswoman Gwendolyn Crump says in a statement that the guard saw the man stab the woman on Friday and chased him. She says the man turned and pointed the knife at the security guard, who opened fire and the man was shot.

Crump says the stabbing was believed to be the product of a domestic dispute.
