On Monday swastikas were spray painted onto a van parked outside of a Jewish girls' school in Stamford Hill, north London.
The incident on Alkam Road occured near to the Beis Malka Jewish Girls' School and the graffiti on parked vehicles included swastikas and the words 'f*** off'.
Police in Hackney are investigating.
The NLMCC to which 'Hackney Muslims' refers is the North London Muslim Community Centre on Alkam Road.
The kind message of soldarity from 'Hackney Muslims' was noticed by Twitter user 'Mike K' who took a screenshot of the exchange and shared it to his followers.
His tweet was shared over 2,000 times within days. Yet his reference to 'Hackney Muslims' as a 'local Muslim group' is slightly misleading.
While @Shomrim purports to be the account for the volunteer Jewish neighbourhood watch group Shomrim, which also has branches in the United States, the account '@HackeyMuslims' is not a local group, by a single human being, self described as:
someone labelled me a 'community activist' ?! ..heck I jus [sic] roam around Hackney checking out the scene across the Muslim community and beyond. ..hardly activist
The Independent has contacted @HackneyMuslims for comment.
