Security camera footage shows a man throwing a Molotov cocktail at a building in the New York City borough of Queens.
Investigators released the video Monday, a day after four arson attacks hit targets across Queens.
The violence occurred over a period of two hours Sunday night.
The first hit a convenience store, the second hit a private home, the third struck a Shi'ite Muslim organisation, and the fourth hit a residence where Hindu services are held.
No injuries were reported.
Police said the suspect was a man driving a silver SUV.
Each of the firebombs was made from a Starbucks Frappuccino bottle.
