A man was found with stab wounds after police were called in the early hours to reports of a disturbance in west London.
A Met Police spokesman said they were called to Westbourne Park Road, in Notting Hill, at around 4.50am on Tuesday.
He said: “Officers attended along with paramedics from London Ambulance Service (LAS). A man, believed to be in his 50s, was found with stab wounds.
“He was taken to hospital. His condition has been assessed as non life-threatening.”
Enquiries are continuing, with forensics officers seen at the scene, but no arrests have been made yet.
The stabbing came amid a night of violence in the capital when two young men were shot dead and a third left fighting for life following a street gunfight in east London.
