Dr Locke was the doctor who looked after baby Moses Dingle when he was rushed to hospital in June 2015. Dr Locke informed Moses' older sister and guardian, Debbie Dingle, that he was suffering from pyloric stenosis and needed an operation. She suggested Debbie contacted her and Moses' mum Charity as Moses was seriously ill. Dr Locke successfully performed surgery on Moses and he went on to make a full recovery.
