Am totally shocked. Really angry on this child's behalf.
I notice that within their statement Plymouth City Council have said
"Sadly, there are people of all ages who know that they can use photographic images to bully, exploit or coerce others, and do so"
What Plymouth City Council don't go on to say is that 'sadly', in this instance, one of the people to use this young girl's image in a bullying and exploitative fashion was the young girl's teacher.
(IMO to show a blow-up image of a bikini clad teenager to 100 of that teenager's peer group, without the subjects permission, is rather bullying and exploitative behavior).
