(Portland, OR) -- Portland Police are warning of an increase in reports of a common scam. The scammer sends an email to the victim with their name in the subject line, their address and phone number. An attached file includes personal information and a photo of their residence. They claim they will send compromising photos or information to everyone on their contact list if they're not paid in a day. Police say the extortion scam almost always goes nowhere. Attachments can contain malware and shouldn't be opened. Police want anyone who lost money to the scam to report it.
