Two 13-year-olds allegedly joyriding in a family car were speeding through a North York intersection early Tuesday morning when they collided with a fuel truck sending the teenage passenger to hospital.

The pair were in the car at a “high rate of speed” going south on Dufferin Street when they struck a fuel truck at Finch Avenue West at about 4:45 a.m., Toronto police said.

A GO Transit bus was also struck after the initial collision.

Paramedics responded and took a male teen to hospital in serious condition, said deputy commander David Viljakainen.

Nobody else was hurt, police said, and there was no breach of the fuel tanker truck.

The boy driver is in police custody, police said.

The busy intersection was closed for the morning rush hour while police gathered evidence.

The Special Investigations Unit is now investigating the incident, Alex Li police spokesperson said. Police would not confirm why the SIU became involved in the investigation.
