Teenager pleads guilty after arson attack on Kenton synagogue

The fire at Kenton United Synagogue was discovered not by worshippers, but by Metropolitan Police officers making security checks at local synagogues, a detail that has sharpened concern about how exposed Jewish institutions remain in north-west London. The 17-year-old British national from Brent pleaded guilty after the arson attack around 23:35 on Saturday, April 18, at the synagogue on Shaftsbury Avenue in Harrow. Minor damage was caused and nobody was injured.

Police charged the teenager with arson not endangering life under the Criminal Damage Act 1971, and he was remanded in custody ahead of an appearance at Westminster Magistrates’ Court on Tuesday, April 21. He was first arrested on Sunday, April 19, along with a 19-year-old man detained at a separate address in north-west London at about 22:10. The older suspect has been bailed pending further enquiries.

The Kenton case sits inside a broader cluster of arson incidents now being investigated by Counter Terrorism Policing. Officers have linked recent attacks on volunteer-led Jewish ambulances in Golders Green on Monday, March 23, an attempted arson at Finchley Reform Synagogue shortly after midnight on Wednesday, April 15, and an arson attack on a Persian-language media organisation in north-west London the same day. Police said several premises connected to Britain’s Jewish community and to those who oppose the Iranian regime had been targeted, and that many of the incidents were claimed online by Ashab al-Yamin, the Islamic Movement of the Companions of the Right.

Deputy Commissioner Matt Jukes said investigators were considering whether Iranian state aggression or criminal proxies were involved, and he said there had been 15 arrests in relation to six incidents targeting Jewish-linked premises in London in recent weeks. Police have also stepped up thousands of additional shifts to protect Londoners, a response that underlines how persistent the threat has become for congregations and the officers tasked with guarding them.

The Community Security Trust said the Kenton attack caused minor smoke damage to an internal room, but no significant structural damage. Still, the symbolism of fire at a synagogue has reverberated well beyond Harrow. Sir Ephraim Mirvis, the Chief Rabbi, described the attack as cowardly and said a sustained campaign of violence and intimidation against the Jewish community of the UK was gathering momentum. United Synagogue president Saul Taylor pressed the Prime Minister to publicly call the wave of incidents “an epidemic of anti-Jewish hate”.

The fear is unfolding against a grim statistical backdrop. The Community Security Trust recorded 3,528 antisemitic incidents in the UK in 2024, then 3,700 in 2025, both the second-highest annual totals ever recorded. For Jewish institutions across London, the recent arrests do not erase the damage already done: each new incident deepens anxiety over whether schools, synagogues and other community sites can stay safe in a climate of repeated attack.
