A sign with a mocking message from a white nationalist group aimed at San Francisco's sanctuary city policies was removed Sunday soon after it was put up above the Yerba Buena Tunnel. 

Those with a group that refers to undocumented immigrants as "illegal invaders" and call themselves Identity Evropa say they put up the sign. 

The banner, which read, “Danger, Sanctuary City Ahead,” could be seen by drivers on the Bay Bridge heading west on Interstate 80. The CHP says the banner was taken down almost immediately.

The group was founded by Nathan Damigo, a 31-year-old Marine and student at Cal State Stanislaus, who made headlines last spring when he punched a woman at a pro-Trump rally in Berkeley.

Identity Evropa also put up a memorial poster in San Francisco after Jose Ines Garcia Zarate was acquitted for the death of Kate Steinle in 2015.
