A six-year-old Bicester boy and his little sister helped save their dad's life during a diabetic fit - by summoning one of Santa's elves.

When Reece Sullivan's dad Paul collapsed semi-conscious on the kitchen floor, the Longfields Primary School pupil knew exactly what to do.

Mr Sullivan's blood levels had dropped dangerously low and he was close to blacking out.

But quick-thinking Reece, who was in the house with sister Ellie, three, dialled 999 to tell a relative his dad, who has to inject himself twice a day with insulin, was ill.

When the two youngsters heard sleigh bells outside, they ran to call for help from members of Bicester Lions Club, who were on their annual street collection.
