"We contained and evacuated the area," Snohomish County Sheriff's Office spokeswoman Shari Ireton said.
A Washington State Patrol bomb squad, which includes law officers from several local police agencies, removed the bottle and took it to the Boom City parking lot behind the casino.
It was unclear what was in the bottle, Ireton said.
The bottle and its contents were destroyed with a chemical explosive, Ireton said.
