Winnipeg police are investigating what they are calling an unthinkable attack that left a three-year-old boy in grave condition.
Police said they were called to a north-end residence early Wednesday and found the boy with serious injuries.
Const. Jay Murray could not provide much information about what happened, but said the assault with a weapon was not random.
Murray said police had a suspect, but no one was in custody.
The assault came just days after a deadly weekend in Winnipeg during which a 14-year-old girl was fatally stabbed at a Halloween party and a baby was injured during a separate shooting.
Murray said the amount of violence involving children is unusual and he expects it will have a large impact on the community.
