A week since Amber Alert issued for missing children, location remains unknown

Surrey R-C-M-P say it's been one week since an Amber Alert was activated for Aurora and Joshuah Bolton, whose whereabouts remain unknown.

Police say they're still concerned for the children's safety after their mother, Verity Bolton, didn't return them to their father after a trip. 

Mounties say the children were last captured on video in Merritt back on July 7th, and are now believed to be with their mother, her boyfriend Abraxas Glazov and her father Robert Bolton. 

Investigators say they're working night and day to find Joshuah and Aurora, and say tips provided by the public are a key part of the investigation.
