A teacher and a classroom assistant carried out a five-month campaign of bullying against a seven-year-old pupil in which they taped her to a chair and shut her in a storeroom, a court has heard.

Rachael Regan, 43, and Deborah McDonald, 41, went on trial today at Bradford Crown Court charged with child cruelty after they "singled out and bullied" the girl at a school in the Calderdale area.

The catalogue of incidents against the pupil, who is now nine, also included sticking post-it notes to her thumbs, tying her shoes on with string, calling her a nickname, kicking her chair, goading her with a biscuit, hiding her doll and tearing up her photograph.

The jury heard that McDonald, the teacher, also made a calendar to give to colleagues which included a number of comments and photographs of the girl.

Simon Waley, prosecuting, told the court that another member of staff had witnessed some of the incidents against the pupil.

He said: "(The staff member) felt that (the girl) was being singled out and bullied by these defendants on a regular basis."

Mr Waley told the jury that McDonald and teaching assistant Regan were jointly responsible for what happened to the girl.

He said: "The prosecution say that they wilfully ill-treated her, in that they pursued a course of conduct in which their systematic treatment of her amounted to bullying and which caused her unnecessary suffering by way of upset and distress.

"Both were playing their part in this course of conduct, even if they did not each play a physical role in each of the acts complained of."
