A teenager who reportedly died after jumping on to a greenhouse while running from chaotic Bonfire Night scenes has been named locally.
Qais Muhammad Ratyal was reported to have injured himself following an incident in Halifax, West Yorkshire, in which youths threw fireworks at each other.
Residents told YorkshireLive that riot police arrived to deal with the chaos on Saturday night, with the 17-year-old believed to have been among the teenagers who then fled the scene.
A resident of Vickerman Street told the newspaper she called an ambulance after seeing Qais had injured himself while running through back gardens around 8pm.
"He jumped on to the greenhouse and that is how he got injured," she said.
He was taken to hospital where he died, police said.
West Yorkshire Police has referred itself to the watchdog, the Independent Office for Police Conduct, over the incident after officers had been called to the street "due to fireworks being set off".
A force spokesperson said: "Police were contacted by the ambulance service shortly before 8:15pm on Saturday evening following reports of an injured male in the garden of a property...
"The 17-year-old male was taken to hospital where, sadly, he died of his injuries. A scene is currently on in the area as officers establish the full facts of what has happened."
