A 50-YEAR-OLD Weston primary school teacher has been charged with 18 further sexual offences against children.

The individual, who the Mercury cannot name for legal reasons, appeared at Bristol Magistrates Court today, where he was charged with 13 counts of sexual assault against a child, four of voyeurism and one count of possessing indecent images of children.

The man first appeared in court in December where he appeared on two counts of sexually assaulting a child and two of abusing a position of trust.

The charges now relate to five children in total.

The teacher was arrested after a seven-year-old pupil told her parents he had been touching her inappropriately in class.

The Mercury cannot name the school, also for legal reasons.

Allegations include that he filmed himself abusing a child while in the classroom.

Thirty officers assigned to the case – which has been declared a ‘major incident’ by police – searched his home, computer and classroom following the initial phone call.

They confiscated 20 memory sticks, and previous prosecutor Kelly Marshall revealed one of them contained video footage of a man, which police believe is the teacher, touching a youngster inappropriately during class.

Experts believe the footage was filmed from underneath a school desk, with other pupils present.

The man denied all allegations when he was interviewed by police, but has yet to enter a formal court plea.

He will appear at Bristol Crown Court next week.
