Sam Altman House

Police and OpenAI officials say a 20-year-old man suspected of throwing a Molotov cocktail at CEO Sam Altman's San Francisco home has been arrested. The police department says the incident occurred shortly after 4 a.m. Friday and that the thrown device set an exterior gate on fire. Police say the suspect fled on foot. Less than an hour later, police were called to OpenAI headquarters, where they said the same person was threatening to burn down the building. No one was hurt, and OpenAI says it is assisting with the investigation. Police haven't publicly identified the man they arrested.

San Francisco District Attorney Brooke Jenkins says that 20-year-old Daniel Moreno-Gama has been charged with attempting to kill the OpenAI CEO as well as a security guard at the residence when he threw the incendiary device at the gate of Sam Altman’s home on April 10. Moreno-Gama was arrested a short time later outside the headquarters of OpenAI, and police said that he threatened to burn down the business. Court documents say the man is opposed to artificial intelligence and had a list of other AI tech executives. Matt Cobo, the FBI's San Francisco Acting Special Agent in Charge said of the incident: “This was not spontaneous. This was planned, targeted and extremely serious."
