An Amber Alert issued early Thursday morning for a six-year-old has been expanded to northern B.C. and into the Northwest Territories or the Yukon, RCMP say.
Mounties say the boy was taken on Tuesday from the hamlet of Valhalla Centre, roughly 63 kilometres northwest of Grande Prairie, Alta.
The Amber Alert is still in effect for everyone north of Grande Cache, up to Chateh, and within the north and west provincial boundaries.
An updated B.C. emergency alert just after 6 p.m. Thursday says the child may have last been seen in Fort St. John, B.C., around 9:30 a.m.He is believed to be with his mother, partner and a four-year-old child .
RCMP Const. Sandra Geiger told CTV News Edmonton the incident stems from a family court order involving Lanakai.
“From what I understand, RCMP were called to assist with the court order, and so from that this incident has transpired,” she said.
Later Thursday, Geiger said RCMP was actively investigating tips from a “highly engaged” public.
Anyone who sees them should not approach and should instead call 911.
