A Jewish man stabbed in the Golders Green attack has told the BBC "it's a very big miracle" he survived.
Speaking from hospital, Shloime Rand said: "I feel like God's given me back my life."
The 34-year-old was stabbed alongside Moshe Shine, 76, in north London on Wednesday.
The BBC understands Essa Suleiman, 45, from south-east London is the man police have arrested on suspicion of attempted murder. He remains in custody.
Rand told the BBC he is thankful the injuries he suffered were not worse.
