It is believed that these victims were targeted because they were Muslim," said Detective Superintendent Paul Waight of the London Police.

The boy is still recovering in serious but non-life-threatening condition, they said, adding that family members of the victims have requested the names of the victims not be released at this time.

According to Waight, the family was waiting at the intersection when a black pickup truck, driven by 20-year-old Nathaniel Veltman, mounted the curb and struck them.

Veltman was later stopped in the parking lot of a mall, where police were able to place him under arrest, according to police.

Veltman has been charged with four counts of first-degree murder and one count of attempted murder.
