A man was stabbed at the center of Chinatown in the middle of the day Thursday, police said.
The man was stabbed in the arm about noon near 7th and H streets NW. Police said two people are in custody.
Investigators said the victim made his way toward the sidewalk, where a good Samaritan helped him until medics arrived.
"He obviously could not control the bleeding. So, I just grabbed his arm, tried to make a tourniquet. Huge wound... you could put your hand in there if you wanted to," said Henry Francis, the man who helped the victim.
The victim's injuries are not life-threatening, police say.
Police blocked off 7th Street NW between H and G streets for about three hours while they investigated. An entrance to the Chinatown-Gallery Place Metro station was also closed during the investigation.
