The Metropolitan Police is investigating seven separate incidents of criminal damage at Jewish premises as linked.
It comes after four synagogues and a private residence in Golders Green had an unconfirmed substance smeared on them, with two occasions of an unknown liquid being thrown towards a school and over a car.
The latest incident was reported to police this morning (September 11), which saw another synagogue targeted with a substance.
Reports of religiously-motivated crimes in the surrounding area have been received on August 15, September 2-4 and again on September 7 and 8.
Det Supt Katie Harber said: “These are revolting and appalling acts and we are urging the public to help us identify the perpetrator.
“Police and local partners continue to carry out extensive CCTV enquiries which have established the same suspect is likely responsible for all seven offences. Detectives and neighbourhood officers are working at pace to identify them.
“We are very aware of how distressing these offences have been for those who have been targeted. We will not tolerate this kind of behaviour.
“We are actively engaging with the local community and remain in discussion with community partners and key stakeholders to provide reassurance and support. Please speak to a local officer with any concerns you have.”
No arrests have been made at this stage.
