Ms Dumbleton said her mother had suffered injuries to her neck and spinal cord that caused a heart attack, and despite the efforts of a passing couple who performed CPR her brain had been starved of oxygen for too long.
She posted a message on Friday which said: “I laid in my mum’s hospital bed and held her close to me till the very end and told her to be brave and not to be scared and that it was ok she could rest now.
“My mum’s organs are being donated and she is saving lives as I write this and that makes my mum a hero!
“I love you mum now forever and always don’t worry I got things from here.”
Ms Dumbleton had said her mother had put up the “fight of her life” and thanked friends, family, police and hospital staff for their “amazing support”.
