London (CNN)Police in London are investigating anti-Semitic graffiti found scrawled across shop fronts, restaurants and a synagogue as a possible hate crime.
Anti-Semitic graffiti sprayed across London shopfronts and synagogue
Images of the Star of David and messages apparently relating to the September 11 attacks were painted on buildings in the north of the city on Saturday evening, authorities said.
"This is clearly a concerning incident and one we are taking seriously," inspector Kev Hailes said in a statement. "We have liaised with our partners in order to remove the graffiti and various enquiries are underway to find who is responsible."
According to the statement, no arrests have yet been made.
Residents posted photos online of the graffiti, which appeared in several different locations in the Hampstead and Belsize Park areas.
The South Hampstead Synagogue, located in a part of London with a large Jewish population, was also targeted.
James Sorene, the CEO of the Britain Israel Communications and Research Centre, said on Twitter that the targets include an "Israeli style cafe" that recently closed down.
The numbers "911" refer to the anti-Semitic conspiracy theory that Jewish people were responsible for the September 11 attacks in New York, Sorene added, describing the grafitti as "chilling."
