A UK Jewish neighborhood watch group alerted authorities on Wednesday to the discovery of a number of swastika posters placed near a playground in Stamford Hill, The Jewish Chronicle newspaper reported.
The group, Shomrim, have urged residents in the area to alert police immediately if they have any information regarding the incident.
Authorities were also alerted to another event Wednesday afternoon when a smeared Star of David was discovered on a barber's shop front in the South London suburb of Subiton, The Chronicle said.
“I went in to speak to the barber who turned out not to be Jewish and he had no idea why someone would do that to him," said Laurence Lando, who is a member of New West End Synagogue in the area and first notified the police to the incident.
"He was actually Afghani himself so it didn’t even make sense to graffiti his shop in that way. But either way it is offensive be you Jewish or not. We called the police and alerted CST and the graffiti was removed immediately."
“It is very unusual, we are a small Jewish community in south London. It is the sort of thing we are used to in north-west London," he added.
