What we know:

Police say firefighters were called to the home near Jones and Leavenworth streets just before 4 a.m. Friday for a fire.

The fire occurred at an exterior gate of the home.

According to SFPD, the fire had "self-extinguished" by the time they had arrived, though officers found evidence of an incendiary device.

It's unclear if Altman was home at the time.

"We deeply appreciate how quickly SFPD responded and the support from the city in helping keep our employees safe," OpenAI said in a statement. 

Police say the cause of the fire is now under investigation.

No injuries were reported.

Altman purchased his San Francisco home in 2020, according to the San Francisco Standard.

After throwing the Molotov cocktail at the home, police say the suspect then fled on foot. 

A short while later, just after 5 a.m., officers responded to a business on the 1400 block of 3rd street, where a suspect was threatening to burn down the building. 

Police say they identified the 3rd Street suspect as the same person who was at the home the hour before. 

The suspect, only identified as a 20-year-old man, was then taken into custody. 

Police say charges are still pending.

OpenAI is headquartered in San Francisco's Mission Bay neighborhood at 1455 3rd Street.
