Rescue crews have found two boots while searching for a six-year-old boy who fell through the ice in the Rivière Noire near Upton, Que., east of Montreal along with his neighbour's dog.
Police said one of the boots belongs to Maxime, who was playing with his older brother, Alexandre, and a third child on the river bank when he fell through the ice around 5 p.m. Monday evening. The other boot belongs to Alexandre.
Alexandre and the friend were trying to pull Maxime out when a neighbour's dog jumped into the water to save the boy. The golden retriever is also missing.
"It would appear that there is a good current at that area and there is a small, thin covering of ice near the shore," Quebec provincial police spokesman Daniel Thibaudeau said Tuesday morning.
Residents asked to check property
The grandmother of the two boys said the family has not slept all night.
"We're scared for the children, and I'm also worried about [the parents]," Pierrette Maurice told Radio-Canada.
Family members joined the ground search Tuesday, but police are asking volunteers to refrain from searching too close to the icy water to prevent further accidents.
Police are also asking people who live along the river, about 80 kilometres east of Montreal, to check their property for any signs of the boy, as there's a "slim hope" the boy made it out of the river.
Thibaudeau said the six-year-old was wearing a green vest with a dinosaur on the front.
A police helicopter is being used in Tuesday's search, along with sniffer dogs.
