Scotland Yard sought to reassure the community on Thursday after a jewellery shop in Stamford Hill was allegedly burgled twice over recent weeks.
The shop was a Jewish business, a police spokesperson told the JC, but Detective Constable Andy Treadaway stressed there was no "information to suggest the burglaries are antisemitic in nature".
In both incidents - which were reported in the early hours of 28 October and 18 November - "the suspects arrived in a car and forced their way in before stealing goods. They then fled in the vehicle," the spokesperson said.
There have been no arrests and enquiries remain ongoing.
"We've spoken to a number of local businesses and communities following these incidents and a substantial investigation is ongoing. We are treating them as linked," said Detective Constable Andy Treadaway.
"While there is no information to suggest the burglaries are antisemitic in nature, we of course understand the considerable community concern and are doing our utmost to identify the people responsible."
Police urged anyone with information, video and images to come forward and called on local businesses to share any CCTV footage.
