Police have arrested four more young boys and charged them with a hate crime in connection to the blaze that destroyed a school bus in Brooklyn over the weekend.

The boys — an 11-year-old, a 12-year-old, and two 14-years-old — were taken into custody on Thursday and have been charged with arson as a hate crime and criminal mischief as a hate crime, according to authorities.

Previously, another 11-year-old boy was arrested on the same charges.

According to cops, on May 8 at about 6:04 p.m. the group of five boys placed cardboard boxes inside a yellow school bus in front of 509 Brooklyn Ave. They then set the boxes on fire, and the blaze spread to the bus causing large damage to the vehicle.

The suspects — who were allegedly caught on surveillance video committing the crime — then ran away from the scene.

The bus involved in the incident belonged to the Bnos Orthodox Jewish School for Girls, CBS2 New York reported.

Although the five boys are now in custody, the investigation remains ongoing, police said.
