A 13-year-old schoolgirl is fighting for her life after allegedly being stabbed in the neck.
Six teenagers have been arrested on suspicion of attempted murder, Humberside Police said.
The young victim was found by passers-by who offered first aid at the side of the A63 dual carriageway in Hessle near Hull at about 6.50am on Friday.
She suffered lacerations to her neck, chest and abdomen and is in a critical condition.
Four boys aged 14, 15, 16 and 17, and two girls aged 14 and 15 were detained soon after in a nearby wooded area.
All remain in police custody as cordons are in place where officers are scouring for clues.
Detective Superintendent Simon Vickers said he believed the attackers knew the victim, adding: “I understand this incident will rightly cause concerns amongst the community and I would like to offer my assurances that as a part of our initial investigation we have six individuals in custody who are all being questioned by detectives.
“At this time, we do believe the attackers knew the victim and inquiries are ongoing to establish the circumstances around the incident.
“The girl remains in hospital in critical condition and her family are being supported by officers at this difficult time.”
Searches also took place near the Hull Humber View Hotel in North Ferriby and wooded areas off Ferriby High Road.
Det Supt Vickers said: “Locals can expect to see an increased police presence over the weekend as my officers provide additional reassurance to residents.”
“If you see them and have concerns, please come and speak to us.
“There are currently cordons in place surrounding the wooded area off Ferriby High Road to allow emergency services to work safely and follow multiple lines of enquiry.
“I would also like to thank the members of the public who came to the aid of the girl.
“They assisted her at the roadside before emergency services arrived.”
Anyone with information, CCTV or dashcam footage should call detectives on 101, quoting log 82 of November 1.
