A 14-year-old boy has been arrested on suspicion of attempted murder after a teenager was stabbed in Slough.
The 17-year-old victim was found in Bantry Road, Cippenham, just before 15:00 GMT on Tuesday.
His injuries are not believed to be life-threatening but he remains in hospital, Thames Valley Police said.
The arrested boy, from Slough, remains in police custody. The force has appealed for anyone with information to come forward.
Det Insp Will Crowther said: "I believe this happened at a busy time of the day and there will be a number of people who would have witnessed what happened."
A Section 60 order, giving officers greater powers to ensure people are not carrying weapons, was put in place after the stabbing but has since been lifted.
