Kirsten Grant was a pupil at Weatherfield Comprehensive during 2000 and the ringleader of a group who taunted thirteen-year-old Sarah Louise Platt when they discovered that she was pregnant. After the Platt family attended a meeting with Mrs Paton, the school's headteacher, Sarah returned to school the following day - to be faced with a life-sized doll falling out of her locker that had been planted by Kirsten. A tearful Sarah blamed her friend Candice Stowe for telling Kirsten (and subsequently, the whole school) about her pregnancy. However Candice tried to explain that she was only trying to defend Sarah after Kirsten had made comments about her becoming "fat and wobbly".
