A teenage boy has died after falling through the roof of a disused mill in Ramsgate, Kent.
Cameron Tidey, 13, fell 20ft (6m) after he climbed on to the roof of the Rank Hovis mill to retrieve his football.
He sustained a massive brain trauma in the fall, and died at the Royal London hospital on Wednesday.
Kent Fire and Rescue Service said they gave Cameron treatment before he was air-lifted to hospital.
"Firefighters gained entry to the building and gave CPR to the youngster before he was given further treatment by paramedics and then transferred to the air ambulance," a spokesman said.
His devastated mum Marina Tidey wrote on Facebook that her family had been left heartbroken by the tragic accident.
"I thought he only played football in Boundary Park but yes, boys will be boys," she said.
She said that Cameron was her 'gorgeous, happy, healthy, fun loving angel' and added that she is going to donate his organs to help others.
"This is something Cameron had said he would like to do and I am so proud of him for it," Ms Tidey wrote.
Cameron attended The Ellington and Hereson School, in Newlands Lane, Ramsgate, where his head teacher Simon Pullen said he was 'bright, hardworking and popular'.
"The school is working with the Local Authority to provide counselling and support for everyone affected by this terrible tragedy and our thoughts are with Cameron's family," Mr Pullen told the Thanet Gazette.
The mill had been standing empty since it was sold off by Rank Hovis around 10 years ago.
