A fourth individual has been taken into custody in connection with last week’s arson attack on ambulances belonging to Hatzolah in north London, according to the Crown Prosecution Service, as reported by the BBC.

Prosecutors told Westminster Magistrates’ Court that the suspect was apprehended this morning at the courthouse itself, where police were seen escorting a man out of the building. Authorities indicated that four people were involved in carrying out the attack.

Earlier that same day, three suspects already charged in the case appeared before the court and were ordered held in custody.

Those charged include two British men, ages 20 and 19, along with a 17-year-old who holds dual British-Pakistani citizenship.

All three face charges of arson with intent to damage property, along with recklessness regarding whether lives could have been put at risk.

The Metropolitan Police later confirmed that a 19-year-old man, previously identified by officers, was arrested at the courthouse on suspicion of arson with intent to endanger life and has been taken into custody.

The attack occurred in the early hours of March 23, when Hatzolah ambulances were deliberately set on fire in the parking lot of a shul in Golders Green. The court was told the destruction caused is estimated at nearly £1 million.

During proceedings, it was stated that there is strong evidence indicating the incident was a “premeditated and targeted attack against the Jewish community”.

In a related development, two additional men, ages 45 and 47, were arrested last week in connection with the case but were later released on bail pending further inquiries, with conditions extending until late April.

Prosecutors added that authorities are continuing to examine whether an Iranian-backed group that claimed responsibility for the incident had any role in the attack.

The investigation is being handled by counter-terrorism police, although officials clarified in a statement Friday that the case “has not been declared as terrorism” at this stage.

The incident comes amid a broader surge in antisemitic activity across London in recent years. Just last month, a Jewish-owned bakery in the city was vandalized following a pro-Palestinian Arab protest, during which demonstrators accused the business of “funding Israel.”

In December, anti-Israel protesters targeted another bakery in London that is owned by Israelis.

The previous month, police intervened to relocate an anti-Israel protest away from St. John’s Wood Synagogue after dozens of demonstrators gathered outside.

A month earlier, an Israeli academic delivering a lecture at City St. George’s, University of London, was disrupted when anti-Israel activists stormed the classroom, shouting accusations and issuing threats.
