Quebec's provincial police, the Sûreté du Québec (SQ), has updated its amber alert for missing 3-year-old Jake Côté. The child was allegedly abducted by a 36-year-old man named David Côté.

"The search radius was extended to the province of Quebec," the SQ wrote in a Twitter post on Wednesday.

New Brunswick RCMP also issued an amber alert for the missing child.

Officers have located the all-terrain vehicle thought to have been used by the suspect and said Wednesday night that he and 3-year-old Jake could now be travelling on foot or in a different vehicle.

The SQ also said Wednesday that the suspect is potentially armed. They've implored the public to report any sightings or suspicious activity by dialling 9-1-1 and to avoid the sector of Sainte-Paule, Quebec, in the Bas-Saint-Laurent to avoid inadvertently impeding the search.

An updated physical description of the child was also released early Thursday morning.

Police believe the child is wearing a "blue T-shirt with silver stripes on the sleeves and the bottom with an inscription of the number 6 or 9 in a blue camo pattern," dark blue jeans and beige boots.

"We are asking people to focus on the physical and clothing descriptions of the persons being sought," the provincial police force said on Twitter.
