Surrey RCMP have launched a dedicated tip line linked to the ongoing BC-wide Amber Alert for 8-year old Aurora Bolton and 10-year-old Joshuah Bolton.

Police allege the two children were abducted by their mother, 45-year-old Verity Bolton, who is believed to be travelling with her father, Robert Bolton, and boyfriend, Abraxas Glazov.

In an update Friday, police say Robert was was picked up by Verity and Abraxas in Chilliwack on June 30, the same day the children were seen with their mother at a downtown Kelowna bar and restaurant.

Surrey RCMP Sgt. Tammy Lobb says police believe Verity Bolton has access to a number of trailers, including a fifth-wheel that seen in Chilliwack on June 30, being towed by a truck without a canopy.

The last confirmed sighting of the two children was at a Merritt gas station on July 7, while the last confirmed sighting of Verity Bolton, was at the Kamloops Superstore on July 15.

Police forces throughout the Southeast District have been working with the Surrey RCMP, who have released a dedicated tip line at 604-599-7676 and an email address to manage all of the tips related to the Amber Alert.

Mounties also say local search and rescue groups and the BC Conservation Officer Service are helping with ground searches while the RCMP’s air unit is keeping watch from above.

“We need the public to stay vigilant and call our tip line or email tips with any sightings,” Lobb said.

“We know they have been using the same truck and they have been towing three different trailers, and we need the public to keep this in mind. It’s also possible the children could be spotted with either Robert Bolton, Abraxas Glazov, or their mother Verity Bolton.”

Anyone who sees the children, the Boltons, or Glazov is asked not to approach them, and to call 911 immediately.
