A leading archaeologist is calling for Bonhams to withdraw two Roman antiquities from a forthcoming London auction, claiming that evidence suggests they were looted.
Dr Christos Tsirogiannis told The Telegraph the two items feature in photographs seized in police raids from two traffickers in stolen artefacts.
One is a Roman portrait head, probably the Emperor Titus, which is estimated to fetch between £50,000 and £70,000.
