Two arrested over Golders Green Hatzola arson

CCTV from the scene, released earlier in the week, showed three individuals, hooded, masked and dressed in black, walking calmly over to emergency vehicles owned by the Jewish volunteer service in the early hours of Monday morning.

One of the suspects was removing something from a bag, before the group was blocked from view by the ambulances.

A few seconds later, flames began to engulf the vehicles, which were parked on a residential street near the Machzike Hadath Synagogue.

Subsequent clips showed an explosion, prompting a larger blaze, as firefighters arrived on the scene.

The Met confirmed it was aware of the presence of a third suspect on the CCTV footage and that its enquiries are ongoing.

Commander Helen Flanagan, Head of Counter Terrorism Policing London, which is leading the investigation, said: “We have been working around the clock since this appalling attack took place and this has led to these arrests being made this morning.

“This appears to be an important breakthrough in the investigation, but we’re also mindful that CCTV footage of the incident suggests there were at least three people involved.

"We fully recognise the local community will still be concerned and our investigation very much remains active and we will continue to work to identify and seek to arrest all of those who may have been involved.

“I’d like to thank the public and particularly the local Jewish community in the area for their continued support and reiterate our appeal to anyone who might have information that could assist with the investigation to get in touch with us.”

Anyone with information should contact the Met on 101, quoting reference CAD415 of 23 March.
