Two people were stabbed in north London on Wednesday in an attack that police have now formally declared a terrorist incident, prompting a major emergency response and an ongoing counterterrorism investigation.

Assistant Commissioner Laurence Taylor, the Metropolitan Police’s counterterrorism chief, said the attack has been officially classified as terrorism as investigators work to determine the motive and whether the Jewish community was deliberately targeted.

Officers were called to Highfield Avenue in the Barnet borough at about 11:16 a.m. following reports of multiple stabbings, according to the Metropolitan Police. Local and armed officers responded alongside the London Ambulance Service.

A 45-year-old man was arrested on suspicion of attempted murder and remains in custody, police said. Authorities are working to determine his nationality and background.

Two men, ages 76 and 34, were treated at the scene for stab wounds before being taken to a hospital, where they remain and are “being looked after,” Taylor said.

Police said the suspect also attacked responding officers before he was subdued with a Taser. No officers were injured.

Counterterrorism officers are leading the investigation, working with security services to establish the full circumstances and develop a complete intelligence picture, Taylor said.

“Whilst I must stress this investigation is at an early stage, we are working quickly to understand exactly what happened,” Counter Terrorism Policing head Laurence Taylor said.

The stabbing unfolded in the Barnet area, near Golders Green, which is known for its large Jewish community. Authorities have indicated the case is being treated as a potentially antisemitic incident, though motive has not been confirmed.

The stabbing unfolded in the Barnet area, near Golders Green, which is known for its large Jewish community, and police said one line of inquiry is whether the attack deliberately targeted London’s Jewish community, though a motive has not been confirmed.

A statement posted on X by Shomrim, a volunteer neighborhood watch group in Orthodox Jewish communities, said a man was seen “armed with a knife” on Golders Green Road and was detained by members before police arrived. The group claimed the suspect attempted to target Jewish members of the public — a detail police have not independently confirmed.

Shomrim said two victims were treated by Hatzola, a volunteer emergency medical service.

Detective Chief Superintendent Luke Williams said officers “swiftly Tasered and arrested the suspect before he could cause further harm,” adding that investigators are “considering all possible motives” and will maintain a visible police presence in the area.

Williams said police are “aware of the significant distress and concern this incident is likely to cause,” and will remain in the area to carry out inquiries and reassure residents.

The attack comes amid heightened concern over antisemitic incidents across the United Kingdom. Authorities are examining recent incidents in London but have not established any direct connection.

British Prime Minister Keir Starmer condemned the violence, calling attacks on Jewish residents “an attack on Britain,” while London Mayor Sadiq Khan said there is “no place for antisemitism” in the city.

Conservative MP Kemi Badenoch said, “Jewish people in our country are under constant attack. This is no longer a growing pattern. There is an epidemic of violence against Jewish people. It is now a national emergency and needs to be treated as such by the Government and public authorities.”

Dov Forman, a Golders Green resident and Holocaust educator, described the attack as part of what he sees as a broader and deeply concerning trend.

“Yet again, terror has been brought to our doorstep here in Golders Green, in the heart of London’s Jewish community,” Forman said. “Earlier today, two visibly Jewish men were stabbed in what is being described as an antisemitic attack. For many, this is not being seen as an isolated act of violence, but as part of a broader and deeply troubling pattern. There is growing concern that extemist rhetoric and Islamist extremism, including calls to ‘globalize the intifada,’ has helped fuel an environment in which hatred against Jews is increasingly normalized, unchecked, and dangerously emboldened.”

Israeli President Isaac Herzog said he was “horrified by yet another violent attack on Jews in broad daylight on the streets of London” and called for urgent action.

“No Jew anywhere in the world should be a target because of their faith,” Herzog said, adding that authorities must act “before the next antisemitic attack occurs.”

Authorities urged anyone with information to contact police as the investigation continues.

The number of antisemitic incidents reported across the U.K. has soared since the Oct. 7, 2023, attack by Hamas on Israel and the subsequent Gaza war, according to the Community Security Trust. The group recorded 3,700 incidents in 2025, up from 1,662 in 2022.
