He allegedly threw the fire bomb at Altman's home just after 4am PST on Friday, before fleeing the scene on foot, according to the San Francisco Police Department. Less than an hour later, police were called to OpenAI's headquarters on 3rd Street after a man allegedly threatened to burn down the building. Police recognized the man as the same suspect in the Altman mansion incident and immediately took him into custody. No injuries were reported.  On Monday, Fox News spotted dozens of FBI agents executing a search warrant outside Moreno-Gama's Texas home.  Moreno-Gama is accused of traveling from the Lone Star State to California to try to kill the OpenAI CEO because of his anti-AI views.

The car immediately fled, but its license plate was captured on a security camera, leading San Francisco police to a residence where they arrested Tom and Hussein on charges of negligent discharge.  Altman, 40, reflected on Friday's terrifying incident on his personal blog, accompanied by a photo of his husband and child which he shared in a bid to deter future attacks.  Sam Altman's Lombard Street mansion was targeted in an alleged Molotov cocktail attack early Friday, according to San Francisco police Moreno-Gama was allegedly carrying a manifesto when he was arrested, described as a 'three-part series' listing other AI executives and their addresses Altman, 40, reflected on Friday's terrifying incident on his personal blog, accompanied by a photo of his husband and child (pictured) 'Images have power, I hope. Normally we try to be pretty private, but in this case I am sharing a photo in the hopes that it might dissuade the next person from throwing a Molotov cocktail at our house, no matter what they think about me,' he wrote.  Altman said that the Molotov cocktail bounced off the house. The bomb set an exterior gate on fire.  'Words have power too. There was an incendiary article about me a few days ago,' Altman continued. 'Someone said to me yesterday they thought it was coming at a time of great anxiety about AI and that it made things more dangerous for me. I brushed it aside. 'Now I am awake in the middle of the night and pissed, and thinking that I have underestimated the power of words and narratives.'
