Police say a man set fire to a Jewish school bus in Williamsburg.

The incident happened last month near Division and Bedford avenues. Police say the suspect got into the parked and unoccupied bus through its emergency door and started a fire that caused damage to the front area of the bus. He then took off.

Mayor Bill de Blasio took to Twitter to denounce the seemingly anti-Semitic act.

"Our city has zero tolerance for violent acts of anti-Semitism," the mayor wrote. "We must stand as one against acts of intimidation."

Police say the suspect was last seen wearing a sweatsuit and dark-colored sneakers. Surveillance video of him was released on Wednesday.

Anyone with information can call Crime Stoppers at 1-800-577-TIPS.
