Suspect Arrested for Allegedly Throwing Molotov Cocktail at Sam Altman’s Home
A 20-year-old male was arrested after targeting Altman's residence and threatening OpenAI's headquarters.
San Francisco police arrested a 20-year-old male suspect early Friday morning for allegedly attacking the home of OpenAI CEO Sam Altman and threatening the company's headquarters. According to police and an internal OpenAI security memo, an individual threw an incendiary device—described as a Molotov cocktail—at Altman's residence in the North Beach neighborhood around 3:45 AM PT. The device caused a small fire on an exterior gate but was quickly extinguished, resulting in minimal damage and no injuries. Less than an hour later, a person matching the suspect's description was confronted by security outside OpenAI's MB1 headquarters in Mission Bay, where they made threats to burn down the building. Officers recognized and detained the suspect at the scene.
OpenAI's corporate security team notified employees of the incident, advising heightened vigilance and warning against allowing unauthorized individuals to tailgate into buildings. The company confirmed it is cooperating fully with the ongoing law enforcement investigation and expressed appreciation for the rapid SFPD response. This event marks the latest in a series of security incidents targeting OpenAI and its staff; the company's San Francisco office was locked down in November 2024 due to an alleged activist threat, and protesters were arrested in February 2025 for locking the facility's front doors. The suspect remains in custody with charges pending, underscoring the heightened security challenges facing high-profile AI executives and their organizations.
