A teaching assistant has been banned from classrooms for two years after telling pupils he had killed more than 250 people as a military sniper.

Scott John Trigg-Turner, 44, made bogus claims to a year eight class in Newport that he had been in the US marines, went by the codename ‘Kill Switch’ and still owned a gun.

A professional standards hearing in Cardiff was told wheelchair user Mr Trigg-Turner also claimed to be a lord, the recipient of an MBE and to have served in Northern Ireland during the Troubles – despite being too young to have done so.

Mr Trigg-Turner denied being unprofessional and had told investigators his words were “misinterpreted”.
