On Tuesday morning, employees of the Yakama Nation's Legends Casino discovered a suspicious device in a trashcan outside the casino main entrance, reported nbcrightnow.com.
Around 10 a.m., a Washington State Patrol bomb squad sent a robot on wheels to the scene, which knocked over the garbage can, revealing the suspected bomb.
That's when officials evacuated 600 patrons and 150 employees from Legends Casino. Other tribal offices, including a housing facility, medical clinic and the Cultural Heritage Center, were placed on lockdown.
Ultimately, it was determined to be a “nondevice,” Cheryl Bishop, special agent and public information officer for the Bureau of Alcohol, Tobacco, Firearms and Explosives Seattle field office, which covers Yakima, told the YakamaHerald.com.
"The safety of the public is first and foremost," Yakama Tribal Chairman Harry Smiskin said.
While Legends reopened Tuesday, it remained mostly vacant that evening.
