The door of a Jewish-owned shop in Hertfordshire was set on fire on Sunday, the Hertfordshire Constabulary announced on Tuesday.
The lower high street shop was also vandalized with graffiti and is being treated as religiously aggravated.
Police appealed to the public for witnesses or any security footage of the incident.
"I would like to make it clear that we do not tolerate hate crime in our communities in Hertfordshire. We are working hard to find the person(s) responsible," Detective Superintendent Mark Clawson said in a statement. "I am especially keen to trace a group of young males who were seen in the area around the time of the incident. If you were one of these people, or think you know who they may be, please get in touch.”
Police do not believe event is linked to arsons in London
As of Tuesday evening, police did not believe that the incident was linked to a series of arsons and attacks against Jewish, Israeli, and Iranian dissident-linked sites in London.
While there was no immediate connection to the London incidents, Campaign Against Antisemitism said on X on Tuesday that the country was still seeing a worrying increase in attacks on Jewish sites.
"This is the fourth report of an arson attack on a Jewish space in the past week alone," said CAA. "This is simply untenable. Arson attacks on the Jewish community appear to happen at a daily rate."
Attacks began with the March 23 arson of four Hatzola ambulances in the Golders Green area. On Wednesday arsons attempted to attack the Finchley Reform Synagogue by placing bottles with accelerant next to the synagogue and throwing a brick at the alleged firebomb. Later that day, an arson attempt was made against the office of Iran International, with suspected arsonists throwing a burning container into the car park of the news outlet. The fire died out on its own. A building that was once the premises of a Jewish group, still with the organization's name on the window, was the target of a Friday arson attempt. Three bottles containing accelerants were placed next to a building and set alight. The bottles failed to fully ignite, but minor damage was caused to the shopfront. The same day, jars with an unknown substance, later revealed to be non-hazardous, were discovered near the Israeli embassy. On Sunday, the Kenton United Synagogue was firebombed, causing minor smoke damage to a room, but no injuries.
Harakat Ashab al-Yamin al-Islamia (HAYI) is a suspected Iranian front group that has claimed responsibility for many of the attacks. By Tuesday night, it did not appear as if any statements by HAYI on the Hertfordshire incident had been published on Islamic Regime-affiliated media.
