Buildings were evacuated at Google’s headquarters in Mountain View, California, on Friday afternoon after a threat was made against the company.

No one was injured and there was no damage to buildings, Mountain View police spokeswoman Katie Nelson said. The incident involved a few buildings, beginning around 3:30 p.m. and concluded shortly before 5 p.m. Both police and Google security responded.

Google didn't immediately have more information to provide. Police didn't comment on the nature of the threat and said they responded out of caution.

While the campuses of Silicon Valley companies aren’t normally considered terrorist targets on the scale of federal buildings or major sporting events, major companies like Google, Apple, and Facebook are prominent symbols of U.S. economic and cultural power.
