A memorial service was held for first-year Oxford University student Chao Cao, 19, last night.

Mr Cao died of a suspected heart attack last week and members of his college, St Hilda’s, gathered at the Jacqueline du Pre building last night to pay their respects.

College principal Sheila Forbes said: “We are shocked and deeply saddened by the sudden death of Chao Cao, a first-year engineering student from Shanghai, from an unexpected cardiac arrest.”
