A 16-year-old boy has died after what is believed to be a stabbing at a school in Aberdeen. The male pupil was taken by ambulance to Aberdeen Royal Infirmary following a "serious incident" at Cults Academy but died a short time later.

Police have detained another 16-year-old boy in connection with the incident, which took place at around 1.30pm within the school premises. The victim has been named as fifth-year pupil Bailey Gwynne.

A Police Scotland spokesperson said: "Enquiries into the circumstances of the incident are ongoing and officers will remain at the scene for the time being. Next of kin are aware."

Police confirmed they are treating the incident as a murder. Chief Inspector Graeme Mackie said: "This is a shocking and extraordinary incident for Aberdeen. Firstly our thoughts are with the family and friends of the boy who has sadly lost his life today.

"A full and thorough enquiry has been launched and there will be a police presence in the area for the foreseeable future. We are working closely with the education authorities and wider community, as I am sure this incident will be felt not only in Aberdeen but much further afield."

An Aberdeen City Council spokesperson added: "We are aware of a serious incident at Cults Academy today. Police are on site. Due to the nature of this incident, we will not be issuing further comment."

Cults Academy said staff were shocked and saddened at the incident, adding the school will provide support to pupils, teachers and parents.

"It is with shock and sadness that we can confirm that a pupil of Cults Academy has died following an incident at the school earlier today," the institute said in a statement "Our heartfelt sympathies are extended to the friends and family."

Scotland's First Minister Nicola Sturgeon expressed her condolences on Twitter.
