LAS VEGAS - PRELIMINARY tests indicate that a package found at a Las Vegas motel contained the toxin ricin, and seven people have been taken to hospitals, authorities said.
Investigators did not believe the substance was intended for an attack.
'This event does not appear to be terrorism related,' FBI spokesman Richard Kolko in Washington said on Friday morning. He said the FBI was assisting local police in the investigation.
Police were called to the Extended Stay America Motel on Thursday and retrieved a package from the motel manager that was determined to be a chemical or controlled substance, Officer Ramone Denby said.
The man who brought the substance to the manager told police he found it in a suite and it did not belong to him, according to the Las Vegas Review-Journal.
Two preliminary tests indicate it contained ricin, Officer Denby said.
Results from further tests by the Centers for Disease Control and Prevention and a second local lab are expected on Friday, he added.
'Ricin has no medical uses other than cancer research,' police Captain Joseph Lombardo said at a news conference on Thursday night.
'An individual citizen other than being involved in cancer research or cancer prevention would not have any legal means or proper means of having that.'
Police cordoned off the area and isolated the room where the substance was found.
Three motel employees and another person were quarantined and decontaminated at the site, then taken to hospitals for further testing, Officer Denby said. All appeared to be in good condition, he said.
Three police officers who had been exposed were also taken to hospitals. It takes between six and eight hours for someone exposed to ricin to show signs of contamination, officer Denby said.
Homeland Security officials joined local police in the investigation. Officials from the FBI, Las Vegas Health District, a hazardous materials team and the National Guard were also at the scene.
Ricin is made from the waste left over from processing castor beans, and can be extremely lethal. As little as 500 micrograms, or about the size of the head of a pin, can kill a human, according to the CDC. -- AP
