derek sawyer did he protect derek slade ? derek sawyer abused children for 40 years, and when his home was raided it contained 7000 images of children 4000 of which were deemed indecent.

I know this much it appears that his schooldays friend who vouched in writing, allowing him to get into a position which enabled him to abuse more children

appears to live on charteris road in Finsbury Park, London N4 by the look of the documentary video.
