A 14-year-old boy has been arrested on suspicion of murder, following the death of a 12-year-old boy who was stabbed in Hall Green, Birmingham, on Tuesday.
The victim was found with serious injuries near Scribers Lane, shortly after 15:00 GMT.
He was taken to hospital but died as a result of his injuries.
West Midlands Police is appealing for information, as well as photo and video evidence.
The force said the boy’s family had been informed and were being supported by specialist officers.
Det Insp Joe Davenport said: “If you were in the area at the time and saw what happened, or think you may have captured any part of what happened on dashcam or mobile phone, it’s vital you get in touch.”
Scribers Lane is a long and busy road, surrounded by houses, shops and local schools, in the suburb of Hall Green.
The attack is believed to have taken place near the railway bridge, which is next to Trittiford Mill Park.
