The owner of a school at the centre of Norfolk's biggest-ever child cruelty investigation died the day after he was given a two-year suspended prison sentence, a coroner said yesterday.

George Robson, 66, who was convicted of a catalogue of abuse against children in his care at Banham Marshalls school, near Diss, died of heart failure on November 13 last year.

On November 12 he was given a two-year suspended sentence after being found guilty of five counts of cruelty to pupils from 1976 to 2002. At about 8.30am the next day he was found by his wife, Sheena Robson, lying on the floor in the hallway of their home in The Street, Bridgham.

The coroner William Armstrong recorded a verdict of accidental death, stating “he died as a result of a fall, but it is likely that it resulted from a cardiac event”.
