A review into the killing of Aberdeen teenager Bailey Gwynne has begun.
The inquiry will focus on the relationship between the 16-year-old and the fellow pupil who stabbed him to death.
At the trial it was revealed that Bailey had been stabbed after a fight broke out over a biscuit.
His 16-year-old killer, who cannot be named for legal reasons, was locked up for nine years after being found guilty of culpable homicide and carrying weapons.
Following the verdict, Aberdeen City Council, Police Scotland and NHS Grampian commissioned an independent review into the schoolboy’s death to identify any lessons that can be learned.
The six-point plan includes investigating the relationship between Bailey and the boy who killed him, prior to the stabbing.
A detailed timeline showing the historical involvement with the killer by the NHS, Aberdeen City Council and Police Scotland will also be developed and a review of the way information between the agencies is shared carried out.
The review will also identify any necessary changes and developments needed within the current youth justice system in Aberdeen and share the report with the Scottish Government to determine if there are “wider issues for the whole of Scotland”.
The review will be headed up by Andrew Lowe, who has been involved in a number of high-profile investigations across the UK including the Hillsborough disaster.
The former lawyer will be granted unprecedented access to any case files and documentation required from all three bodies to reveal the exact details of what happened on the fateful day of October 28.
The outcome of the review will be published in September.
