(Portland, OR) -- The Multnomah County Sheriff's Office is receiving more reports about the jury duty scam. In one case, the victim lost 15-hundred dollars. The scam caller poses as a sheriff's lieutenant or sergeant and claims the victim has missed a grand jury summons and must pay a fine or they'll be arrested. They use pressure tactics and try to keep the person from calling family or friends for advice. They say the victim can get reimbursed from the sheriff's office. If you're contacted by one of these people, don't send money. The sheriff's office never conducts a warrant service or payments of fines over the phone. If you're a victim of the scam call the sheriff's office non-emergency number.
