Vehicles have been daubed with swastikas near a Jewish girls’ school in Stamford Hill.
Pictures posted on Twitter by the neighbourhood watch group, Shomrim, also showed “F*** off” had been scrawled on one the vans targeted.
Shomrim said: “This was noticed this morning. The vandalised vehicles were parked opposite the entrance of a Jewish girls’ school.
“Young schoolchildren and their parents were shocked to discover the offensive graffiti.”
In a separate case, Nazi stickers posted on lampposts and doors were spotted in Liverpool streets on Remembrance Sunday. Merseyside Police confirmed officers are investigating.
Figures have shown a jump in race or religious hate crimes recorded by police in the weeks after the EU referendum.
The number of racially and religiously aggravated alleged offences logged by forces in England and Wales in July was 41% higher than in the same month last year.
The number fell in August, but remained at a higher level than prior to the referendum.
Speaking at a conference at City Hall, London Mayor Sadiq Khan called for an end to the politics of division, warning whole communities are feeling “increasingly disconnected”.
Khan said: “We have seen major political upheaval around the world in recent months, with the EU referendum here in the UK and the presidential election in the US.
“This has shown how politics is becoming more and more polarised with whole communities in cities across the world feeling increasingly disconnected and estranged from national politics.
