BROOKLYN - A second 11-year-old has been arrested in connection with a school bus fire Sunday in Crown Heights.

Earlier this week, another 11-year-old was arrested for his alleged role in the fire. Police made it clear that more arrests would follow. They announced Thursday that a second boy was in custody.

Surveillance cameras appear to capture the boys setting a bus parked outside of a Jewish high school on fire, igniting some sort of cardboard inside the bus before fleeing. No one was hurt.

Investigators say all indications point to the incident being a hate-motivated arson.

Police are still looking for four more boys who were involved in the fire.
