A 29-year-old man has been arrested on suspicion of starting the Pacific Palisades fire in Los Angeles that killed 12 people and destroyed more than 6,000 homes in January, BBC reported.
Evidence collected from Jonathan Rinderknecht's digital devices included an image he generated on ChatGPT depicting a burning city, justice department officials said.
The most destructive blaze in Los Angeles' history, it was sparked on 7 January near a hiking trail overlooking the wealthy coastal neighbourhood.
The Eaton Fire, ignited the same day in the LA area, killed another 19 people and razed 9,400 structures. The cause of that fire remains unclear. Mr Rinderknecht is due in court in Orlando, Florida, on Wednesday, according to BBC.
