The head teacher of a north Wales school has been fined £12,500 and ordered to pay £7,500 in costs after being found guilty of health and safety breaches.
Three-year-old Kian Williams died in hospital just over a month after he fell down steps at Hillgrove School, an independent day school for children aged three to sixteen in Bangor.
A health and safety investigation into the boy's death revealed shortfalls in the levels of supervision for pre-school children at the school, which resulted in him being able to enter an area that was classified as off limits.
Health and Safety Executive inspector Steve Scott stated: "On the day of the incident there was one member of staff supervising 59 pupils with an age range of three to 11. This was well out of line with accepted ratios found elsewhere."
Mr Porter was prosecuted because he was the employer and, as such, had primary responsibility for health and safety matters, he added.
