U.S. federal agents have arrested a Saudi national who was an OpenAI engineer and charged him with installing a hidden audio recording device in an executive conference room at the AI company, the Justice Department said on Tuesday.

The case highlights ?growing security concerns around sensitive AI research as companies and governments compete fiercely for the talent and technology that ?could confer economic ?and strategic advantages.

Abdulrahman Alfozan, 35, had worked as an engineer at OpenAI since July 2025, ?the Justice Department said in a statement. An email sent to an address associated with that name did not elicit a response, and it was not immediately clear who his lawyer was.
