Two teenagers are recovering after being stabbed in north London in attacks which are being linked by the Met police.
Officers found a 17-year-old boy injured in Fairbridge Road in Upper Holloway, Islington, at about 17:35 BST on Monday.
He remains in a serious but stable condition.
Ten minutes later a man believed to be 18 years old was found stabbed less than half a mile away in Sussex Close.
His condition is said to be no longer life-threatening.
No arrests have been made. Police said there would be an increased number of officers in the area.
A Section 60 order - which gives officers the right to stop and search anyone - was authorised for the borough of Islington until 07:00 BST on Tuesday.
