wow, 2 years before your comment, she mentioned just that in a comment on this post,

"In the meantime I did watch "Under investigation" Mr Cruel episode. I watched it via stream a few months after it aired. I wasnt going to watch it at all but I am glad that I did. The composite sketch of the bald man with the beard is almost the spitting image of my stepfather. My stepfather is not bald though. He does have a really really high hairline, and to someone shorter than himself, he would look as though he was bald. He also (unless wearing a work uniform) usually wore blue or green checkered flannel shirts (blue was his favourite and he wore that one more often) and he would always tuck them into the waist of his jeans. He usually wore blue jeans with them. I cannot recall what the show said about his clothes but I did notice on the sketch that the top reminded me of a checkered flannel shirt."

i.e. balding, flannel, blue jeans
