Facebook Inc. (Facebook) ordered four buildings to be emptied, while two individuals were monitored following fears of nerve agents, Sarin, yesterday.
The order was issued after a package received by social media companies located in the Silicon Valley, found to be positive toxic content.
Menlo Park, Jon Johnson, the city that houses the Facebook building, said those who received the suspicious packaging at 11am (local time), did not show any signs of Sarin.
“Facebook has tested all the packs received and the test results are positive, so they only follow the standard protocols already set.
“At this time, we are still waiting for confirmation whether it (the test) is right or vice versa,” he said.
Meanwhile, Facebook spokeswoman Anthony Harrison said the company was evacuating four of his buildings, following a test result was positive and was working with the police to investigate the matter.
“The authorities have yet to identify the material found. So far, three of the empty buildings have been re-entered, “Harrison said.
In addition, a spokesman for the Federal Bureau of Investigation (FBI) said several agents from his San Francisco office were also deployed to the site to assist in investigations.
Sarin is a toxic compound that can affect the nervous system and is often used as a chemical weapon.
Exposure to Sarin can lead to death.
