(CNN) A California synagogue has been vandalized with anti-Semitic graffiti less than a week after a gunman killed 11 Jewish worshipers in Pittsburgh.

Someone spray-painted "F*** Jews" early Wednesday on the wall of Beth Jacob Congregation in Irvine, police said.

The Irvine Police Department posted a surveillance-camera video of a man in a hoodie spraying the exterior of the synagogue.

Police said officers will increase patrols around the city's Jewish organizations.

"IPD has reached out to its partners in the Jewish community to reaffirm the Department's commitment to protecting their members, houses of worship and educational institutions," the department posted on Facebook.
