Police in Burnaby are dusting an apartment mailbox for fingerprints after thieves made off with a haul of holiday mail.

Investigators say some noise woke up a resident in the 5100 block of Imperial Street.

She then spotted two men with big backpacks on, rifling through the mailbox and helping themselves to stacks of personalized envelopes.

"With Canada Post announcing they're doing away with home delivery, we're opening ourselves up to more group mailbox thefts because there will be a lot more mail in concentrated places," said RCMP Sgt. Dwayne Beckerleg.

Police are reminding the public to register and insure all valuable mail, or use other delivery services such as e-mail or gift cards and personalized greetings.
