Its Liam here, I am sorry to be writing the post I never wanted to write. I was sent this email by Adrian' dad Keith Sudbury:
Adrian Sudbury died peacefully in his sleep with his dad Keith and mum Kay last night.
Keith Sudbury said: "Every parent thinks their son or daughter is special and we are no different.
"Adrian touched all who knew him. We're very proud of all his achievements in tragically such a short time.
"Kay and I hope that all Adrian's good work will be continued by all those who knew and loved him."
There will be a private family funeral followed by a service of remembrance at Sheffield Cathedral at a date to be confirmed.
I'm sure you will all join me in offering you condolences to Adrian's family and friends at this very difficult time.
