The Chinese police have detained a man for allegedly using ChatGPT to create fake news  and spread it online.

Local media reports said it is the first criminal case related to AI chatbot.

According to a statement from police in the northwest province of Gansu, the suspect allegedly used ChatGPT to generate a bogus report about a train crash, which he then posted online for profit. The article received about 15,000 views, the police said in Sunday’s statement as quoted by CNN.

ChatGPT, developed by Microsoft (MSFT)-backed OpenAI, is banned in China, though internet users can use virtual private networks (VPN) to access it.

Gansu authorities said the suspect, surnamed Hong, was questioned in the city of Dongguan in southern Guangdong province on May 5, reports CNN.

“Hong used modern technology to fabricate false information, spreading it on the internet, which was widely disseminated,” the Gansu police said in the statement.
