Antisemitic graffiti was found daubed on two locations in southeast London the day before Holocaust Memorial Day.
A bank and a Caribbean takeaway were defaced with a Swastika and a Celtic cross, which symbolises white supremacy.
The Charlton branch of Barclays bank had the word "Jews" painted on its window along with the Celtic cross and the Star of David.
After the graffiti was daubed on Saturday evening, Greenwich council leader Danny Thorpe said he was "disgusted and appalled" to see it.
