MENLO PARK, Calif. - A Facebook mail processing warehouse near company headquarters was evacuated Monday as officials work to determine what caused mail to test positive for the nerve agent sarin. Menlo Park Fire Marshal Jon Johnston said Monday that incoming mail undergoing routine processing by machine tested positive for sarin, but that there are no reports of injuries at the Silicon Valley site. “We’re just doing verification.” The FBI is assisting in the investigation, as is common in incidents such as this one. Facebook spokesman Anthony Harrison said four buildings were evacuated and that three have been cleared for people to come back in. The suspicious package was delivered around 11 a.m. to one of the company’s mail rooms, he said.
