No nerve gas has been found at an American office of tech giant Facebook. It turned out to be a bogus alarm, says a spokesman for the fire department.
Individual sensors at Facebook’s headquarters seemed to detect the nerve gas sarin in two large mailbags.
An extensive investigation now shows that it was not about the nerve gas. Facebook’s post sensors are said to have raised a false alarm.
The sensor report caused panic at the American headquarters of Facebook. Four officers were evacuated as a precaution.
Two employees at Facebook came into contact with the post with the alleged nerve gas. It turned out earlier that they had no symptoms.
