BELLEVUE, Wash. (AP) — A 30-year-old Seattle man was killed and another man wounded in a shooting at a crowded bar in Bellevue, Wash., early Monday, police said.

The shooting broke out just after 1 a.m. at Munchbar at Bellevue Square, an upscale shopping center about 10 miles east of Seattle, said Carla Iafrate, a spokeswoman for the Bellevue Police Department.

Police officers were outside the bar when gunfire erupted because a large crowd had gathered there, she said.

More than 600 people were inside the venue at the time of the shooting. “It was a very complicated scene,” Iafrate said.

The wounded man was taken to a hospital. Iafrate did not immediately know his age or hometown.

The shooting appears to be an isolated incident. No one has been arrested, and investigators were trying to put together a description of the shooter, she said.

No officers were involved in the shooting.

Witnesses described a chaotic scene, telling local media they dove for cover or hit the floor when they heard gunshots.
