Police in Oakland are investigating who’s behind fliers depicting a swastika on a Jewish councilwoman’s forehead.

The Oakland Tribune reports the fliers were plastered throughout Councilwoman Libby Schaaf’s Montclair district throughout this weekend. The posters read “Stop Schaaf. Stop the DAC,” referring to the city’s plan to build a one-stop surveillance center for police and firefighters.

Proponents say the hub will improve emergency response efforts, but critics worry it could threaten privacy.

Schaaf told the newspaper that as a person of Jewish heritage, she found the fliers particularly hurtful.

She said she was surprised she was being targeted because she has expressed concerns about the center and supported initiatives aimed at preventing privacy abuses.
