A 16-year-old boy has died following reports of a “disturbance” at a beach in Ayrshire.
He was found seriously injured by officers at Irvine Beach at around 6.45pm on Saturday, Police Scotland said.
The teenager, from East Kilbride, South Lanarkshire, was taken to hospital but died in the early hours of Sunday.
Officers believe the incident may have been filmed and have urged witnesses and anyone with information or mobile phone footage to come forward.
Detective Chief Inspector Campbell Jackson said: “An extensive investigation is under way to establish the full circumstances surrounding this death.
“Our officers are supporting the boy’s family at this very difficult and heartbreaking time.
“From our investigation so far, we know there were a number of people on the beach around the time of the disturbance.
“We believe several of them were filming at the time and may have footage of what happened.
“I would urge people to review the footage they have and contact police if they think the footage captured could be of significance to our investigation.”
This can be submitted anonymously, the force said.
