More than 20 houses and vehicles were vandalized with anti-Semitic graffiti, including swastikas, in north London on Sunday, Britain’s Jewish News reported.

The attacks took place on Osbaldeston Road in Hackney during the evening. Locals woke up Monday morning to find the Nazi symbol drawn onto window panes, cars and a private ambulance. Shomrim, the Jewish neighborhood watch group, posted photos of the vandalism on Twitter. One photo showed swastikas drawn on the hood of a car beside the words “Jew” and “Sionist (sic) Out.”

“We are committed to bring a stop to these senseless and mindless acts of vandalism, and are working closely with the police investigation to assist in every possible way,” said Shomrim coordinator Barry Bard. “Similar swastikas have appeared in the same area over the past few weeks. Police are taking these incidents very seriously and are treating it as hate crime. I urge anyone with information to call 101.”

Hackney police inspector Jeff Bull said anti-Semitism or racism of any kind will not be tolerated, Jewish News reported. He added, “We are doing our utmost to trace and bring to justice the suspects involved in this racist graffiti as well as reassure all of our communities.”
