Police share photos of men who may be travelling with B.C. Amber Alert suspect

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

On the third day of an ongoing Amber Alert in B.C., the Surrey RCMP Serious Crime Unit launched a tip line and dedicated email address to handle tips related to the case.

The detachment also released photos of two men believed to be travelling with a mother and her two children.

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.

Surrey RCMP spokesperson Sgt. Tammy Lobb told CTV News police believe the group has been travelling via backroads.

"(The mother) is taking steps not to return the children and not to communicate and possibly evade the police," said Lobb.

On July 15, the mother was seen grocery shopping in Kamloops. The children were not present. Their truck was pulling a horse trailer at that time.

The children were due to be returned to their father on July 17, but that did not happen. Surrey RCMP were notified that the kids were missing on Tuesday, July 18, and issued the Amber Alert the following day.

Mounties are now directing tips related to the Amber Alert to a dedicated phone number: 604-599-7676. Tips can also be provided by emailing [e-mail], police said.

Lobb said police have received reports of sightings from as far away as Alberta and Saskatchewan. Investigators are working with local agencies to pursue leads wherever they are reported, she added.

Asked if she had a message for the mother and the other adults in the group, Lobb urged them to call 911 or report to the nearest police station with the children.

"If you're hearing this right now or you're seeing this right now, the police and family members of the children are concerned for the children's well-being," she said. "We need to ensure the safety of the kids."
