Anti-racism groups are to hold a vigil on Monday after antisemitic graffiti was daubed on a synagogue and several shopfronts in the area.
Over 100 Facebook users have confirmed attendance to the gathering at 5.30pm at 80 Rosslyn Hill, but no mainstream communal groups are involved.
The author Michael Rosen and Islington Labour councillor Michelline Safi Ngongo are billed to speak at the vigil hosted by the groups Stand Up To Racism, Love Music Hate Racism, United Against Fascism, and Student Stand Up To Racism.
The Metropolitan Police said in a statement at the weekend it is investigating a racially motivated hate crime after receiving a report of the graffiti at 11.30pm on Saturday.
A Star of David and the numbers “9.11” were spray-painted at locations in Hampstead and Belsize Park, including South Hampstead Synagogue and the restaurant Cafe Hamsptead.
No arrests have been made but enquiries continue, according to the police statement released on Sunday.
Anyone with information is asked to call 101 quoting CAD 7282/28Dec or anonymously to the independent charity Crimestoppers on 0800 555 111.
