“We are deeply saddened by the devastating news about Jasmine” Miss Talbot said. “This has greatly upset our school and the local community and she will be truly missed by everyone who knew her.
“Jasmine was a much loved and loyal friend to many and particularly enjoyed her time spent in the photography studio, showing real passion for this subject.
