A fifth suspect in the London Hatzola ambulance arson case was charged in the torching of the ambulances in Golders Green in March.

Subhan Ahmed, a British citizen from Walthamstow in northeast London, was “charged on Monday, 8 June, with assisting an offender, contrary to section 4 of the Criminal Law Act, 1967,” the Metropolitan Police said in a statement. “Ahmed has been bailed with strict conditions and is due to appear at Westminster Magistrates’ Court on Tuesday, 16 June.”

The other four defendants are charged with committing arson, destroying or damaging property and being reckless as to whether life would be endangered, according to police. They attended a hearing at the Old Bailey on April 24 and are being held in custody until their trial next January.

On March 23, four ambulances belonging to the Jewish volunteer ambulance group Hatzola were torched in what appears to be a targeted hate crime in Golders Green, London.

At 1:35 a.m., three individuals set fire to the ambulances, while a fourth accomplice waited in a getaway car. Gas canisters in the vehicles exploded, causing damage to nearby buildings and a synagogue and resulting in about £1 million worth of damage.

The Metropolitan Police Counter Terrorism Command investigated the case. Authorities are probing a possible link to an Iran-backed group, Harakat Ashab al-Yamin al-Islamia, that has claimed responsibility for the ambulance arson attack and several other recent attacks in London.
