A teenager has been remanded into custody after he appeared in court charged with attempting to murder a 13-year-old girl and possessing a samurai sword.
The 14-year-old was arrested after a girl was found with life-threatening injuries near Hull on Friday morning.
The boy, who cannot be named because of his age, appeared at Hull youth court on Monday morning, where the district judge Mark Daley remanded him into youth detention.
During the ten-minute hearing, the boy stood in the glass-fronted dock accompanied by two security guards, and spoke only to confirm his name, date of birth and address.
The boy is accused of attempting to murder the girl, who also cannot be named, and possession of a bladed article, namely the sword.
The girl was found with serious injuries at the side of the A63 dual carriageway in Hessle, near Hull, at about 6.50am on Friday morning, Humberside police said.
She remains in hospital in a critical but stable condition, after sustaining stab wounds and lacerations to her neck, abdomen, chest and back, police said.
Six teenagers were initially arrested on suspicion of attempted murder on Friday. They were found in a wooded area close to the scene.
Three teenage boys aged 15, 16 and 17, and two girls, aged 14 and 15, have been released on police bail, the force said.
Det Supt Simon Vickers said on Saturday that those arrested in connection with the incident were known to the victim.
The boy is scheduled to appear again at Hull crown court on Friday.
