SAN FRANCISCO (CBS SF) — Police in San Francisco on Monday warned residents of phone scammers claiming to be police and attempting to get people to pay fines on outstanding warrants or crimes.

In a release issued by the department Monday, police said they have learned of phone scams making such demands with perpetrators sometimes using technology known as “caller ID spoofing” that makes it appear than an SFPD phone number or other official looking phone number is making the call on the victim’s caller ID.
