Police are searching for signs of a family of four reported missing by a relative after loved ones lost contact on Monday.

The Andersons were last seen on Sunday, and last spoken with the following day. Surrey RCMP said their vehicle was captured on surveillance camera at 2 p.m. Tuesday, but the parents and their two children haven't been seen or heard from since.

It's possible they could be driving to Alberta, Mounties said in a statement Wednesday. They have also been known to frequent Minoru Park in Richmond.

Mounties are asking for the public's help to locate the Andersons. They provided descriptions of the family members, but otherwise have not made public any further details.

Their vehicle is a 2002 tan Toyota Sienna minivan with Alberta licence plate BGZ 2221.

Anyone with information on their whereabouts is asked to contact Surrey RCMP at 604-599-0502, or Crime Stoppers anonymously.
