Two people were stabbed in north London on Wednesday, police said, adding that a man was arrested after reports of a suspect seen running with a knife in the Golders Green area.

Emergency services were called to the Golders Green area, which is in the heart of the Jewish community in London, after reports of a man seen running with a knife.

"A 45-year-old man was arrested on suspicion of attempted murder. He was taken into custody, where he remains. We are working to establish his nationality and background," the police said.

According to a local Jewish community security organization, the suspect was attempting to attack passersby.

The group said its volunteers responded quickly and nabbed the individual before police arrived.
