Amber Alert: Children potentially taken 'off the grid' after pre-planned abduction, RCMP say

Update: The two children who were the subject of a July 19 Amber Alert have been found safe. 

As an Amber Alert in B.C. stretches into its sixth day, police say the alleged abduction of two children was likely pre-planned and that the adults may have taken the kids "off the grid."

The children are believed to be travelling with their mother and her boyfriend, as well as their grandfather.

Police have released photos of all the adults suspected to be travelling with the children, as well as the children themselves.

In Monday's update, the Surrey RCMP say they have received credible information that suggests the group is likely living "in trailers somewhere in a rural area."

“We need the public to be alive to the information and photos we have shared and to be our eyes and ears and continue to call us with any tips and possible sightings," RCMP spokesperson Sgt. Tammy Lobb wrote in a news release.

So far, police say they have received more than 180 tips but that there have been no confirmed sightings outside of B.C. The last time the children were seen was on July 7 at a gas station in Merritt. The last time their mother was seen was on surveillance video at a grocery store in Kamloops on July 15.

The children normally reside with their father in Surrey, but they left with their mother on June 28 for a planned vacation to B.C.'s Okanagan region and were not returned when they were due to be on July 17.
