A man has been arrested after a young child was stabbed in north west London, police said.
Officers were called by the London Ambulance Service at 1pm on Friday to an address in Larch Road in Cricklewood.
“Officers attended and found a young child suffering from stab injuries," a spokesman said.
"The child was taken to a London hospital; their condition is not believed to be life-threatening.
"An injured man, aged in his 30s, was also taken to hospital where he remains. His condition is not believed to be life-threatening."
The man was arrested on suspicion of attempted murder and officers remain in attendance at the hospital, police said.
“It is believed the victim and man arrested are known to each other," the statement added.
Police said they were not disclosing the age or gender of the child.
Scotland Yard said the Met’s Directorate of Professional Standards has been informed of the incident due to previous police contact with the man.
Superintendent Tim Alexander, of the North West Command Unit, said: "This is clearly an incredibly shocking incident that has left a young child seriously injured and we are working urgently to understand the full circumstances.
"We are not looking for anyone else in connection with the incident and we are satisfied that there is no risk to the wider public."
