A young child was among four people hurt in a shooting in north London, police have said.
Shots were fired in Energen Close, Harlesden, at about 21:45 BST, Scotland Yard said.
The child and a man were taken to hospital with gunshot injuries, the Metropolitan Police confirmed. Both are in a critical condition.
Another male victim and a woman sustained non life-threatening injuries, the force said.
No arrests have been made and police have appealed for witnesses to come forward.
A Section 60 order was in place for the borough of Brent until 07:00, and a dispersal zone has been authorised for the Harlesden area, the force added.
Forensic officers continue to examine the scene and there will be additional police patrols in the area overnight.
