Mr Prentice was a Muggle who lived in Little Whinging in the 1990s. In the evening of 2 August, 1995, after Harry Potter and Dudley Dursley were attacked by Dementors, Arabella Figg told Harry, a wizard to keep his wand out in case of another attack, not minding the presence of Muggle Mr Prentice as they crossed Wisteria Walk.
