An individual threw an "incendiary device" at the San Francisco home of OpenAI CEO Sam Altman early on Friday morning, according to police and an OpenAI spokesperson. The attack damaged an "exterior gate" and caused no injuries.

Less than an hour after the incident, a 20-year-old man who police say matched a description of the firebomber was arrested near OpenAI's headquarters after allegedly "threatening to burn down the building."
