Two men and a woman were arrested for reportedly breaking into mailboxes in Fairmont Hot Springs, Windermere and Invermere on Saturday.
Police said the three suspects were seen trying to break into a mailbox in Spillimacheen and took off in a black Mitsubishi SUV.
They were quickly located by the Golden RCMP.
Police officials said the vehicle was stolen out of Calgary and evidence of mail theft was located inside.
According to the Golden RCMP, a sawed-off shotgun and ammunition were also found.
“The 30-year-old man was found to have had four outstanding warrants out of the Columbia Valley and has since been arrested by Calgary Police in relation to another ongoing investigation,” said Cpl. Michael Wilson of the Golden RCMP.
“We are thankful for the proactive reporting by our community members who were instrumental in facilitating these arrests.”
All three suspects were arrested for possession of stolen property.
The investigation is still underway.
