Lauren Cox, 27, was teaching in south London, when she embarked on the relationship with the boy, who cannot be named for legal reasons. She appeared at Croydon Crown Court today, where she admitted five charges sexual activity with a boy aged between 13 and 17 while in a position of trust.
Cox was arrested after the pupil admitted the abuse to his parents, who then contacted the head teacher of the school, who in turn alerted social services.
