Clinton Roberts, 39, says teachers at John Cabot Academy in Kingswood turned his 11 year-old son away from the dinner hall on the basis he wasn’t wearing a face covering.

The cases have been identified in recent days at John Cabot Academy and, as a result, 60 students in Year 7, 25 pupils in Year 10 and around 40 in Year 8 are self-isolating.
