A 12-year-old boy suffered a fractured toe on his right foot during a brief interaction with members of the Guelph Police Service at a residence on Saturday evening, said the Ontario Special Investigations Unit (SIU) who are now investigating the incident.

Jasbir Brar, SIU spokesperson, said the youth received stitches at Guelph General Hospital as a result of his injuries.

Guelph police said officers were at the residence for a "family problem."

SIU investigators have so far identified one officer who is believed to have been involved in the cause of the injury, and two officers who may have been witnesses. No further details on what happened are being released, as the SIU investigation is in its early stages.

The youth's injuries were considered "serious" under the Regulation of the Police Services Act.

The SIU is called in whenever police officers are involved in incidents in which someone has been seriously injured, dies or alleges sexual assault.
