Police say they have made more than 100 arrests and laid more than 300 charges in a national child exploitation crackdown, with some help from device-sniffing dogs.

Officers acted in self-defense when they repeatedly struck a man who suffered a “serious” fracture while in a Brampton holding cell, Ontario’s police watchdog says.

Peel Regional Police confirmed it is investigating a 2014 sexual assault allegation involving eight former Ontario Hockey League players. TSN/CTV first reported the allegations in October. Peel police said Wednesday their special victims unit is conducting an ongoing investigation into the matter.
