Police are searching for two 12-year-old girls reported missing after a walk to a local bus stop, Scotland Yard said.
Friends Wiktoria Popiel, from Wood Green, and Vitalija Sidlauskaite, from Tottenham, were last seen together on Morley Avenue in Wood Green around 5pm yesterday.
Wiktoria was walking Vitalija to a bus stop on nearby Lordship Lane but did not return home.
The Metropolitan Police said they may have got on a bus towards Tottenham or have gone to the ice rink at Alexandra Palace.
A police spokesman said: "Their disappearance is completely out of character for both girls and they have never gone missing before.
"Their families and police are extremely concerned for their welfare and urge anyone who sees them or who has information about their whereabouts to call police on 101."
Wiktoria was wearing glasses, a brown jacket with fur around the hood, blue jeans and blue Adidas trainers. She speaks English and Polish.
Vitalija was wearing blue jeans and a black jacket and speaks English and Russian.
