Police take down stabbing, arson suspect at Maryland's National Harbor

Police say around 8:20 a.m. officers responded to a stabbing call, where a man and a woman were found with "critical stab wounds."

"Before fleeing that scene, the suspect also set fire to the apartment," Prince George's County Police Department Chief Malik Aziz said during a media conference. "Officers learned the stabbing was domestic-related, and the suspect was known to the victims."

Less than two hours later, "Officers responded to the National Harbor where they encountered the suspect in that earlier stabbing at St. George Blvd and Potomac Passage. The suspect was still armed with a knife and moved towards an officer."

No officers were injured in the incident.

The stabbing victims are in critical but stable condition, police say.  

Investigators have not yet confirmed the relationship between the stabbing victims and suspect. Identities have not been released.
