Police in Ontario and Quebec are warning about a dangerous new online challenge.
Dubbed 'The Momo Challenge' participants are sent a photo of a woman's sculpture through the messaging app WhatsApp. They are then invited to contact an account which sends out disturbing images and potentially dangerous instructions.
The victims are then told that failing to follow the instructions could result in sensitive information being released and references a 'curse.'
So far the challenge has been linked to the death of a 12 year old in Argentina.
