LAS VEGAS - Las Vegas police downplayed the discovery of the toxic substance ricin in a hotel room, saying no one was harmed and they weren't looking for suspects.
Ricin, used in cancer research, was found Thursday by a man cleaning a suite at an Extended Stay America hotel, the Las Vegas Review-Journal reported Friday.
The man, saying the material wasn't his, took the toxic substance to the hotel manager's office and the manager called authorities, said Joseph Lombardo, a Las Vegas police captain and head of the local Homeland Security Bureau.
The man and three hotel employees were taken to a hospital as a precaution, Lombardo said. The hotel was evacuated.
Preliminary tests indicated the substance was ricin, a deadly toxin extracted from castor beans.
"Ricin is very serious," Lombardo said. "Something the size of the head of a pin can be deadly."
Officials said they didn't consider the incident a terrorist threat.
"We don't know that there was any criminal intent on anybody's part," Las Vegas police Sgt. John Loretto said. "It could have been somebody that was reading a book who wanted to try to make something."
