5 Celebrating Birthday Stabbed at DC Bar

Police in Washington, D.C., were searching for a suspect who stabbed five people inside a restaurant in the northwestern part of the city.

The stabbings happened at McFadden's Restaurant and Saloon -- about a mile from the White House -- shortly after midnight Saturday, according to police. The restaurant remained closed Saturday afternoon.

The father of one of the victims told ABC News affiliate WJLA-TV that the victims grew up together and were at the bar celebrating a birthday.

The victims suffered serious injuries but were expected to be released from the hospital soon, police said.
