The pair, who were trading in the Bure Park area of Bicester on Monday evening, did not have valid pedlar’s certificates.

Police did not say what they were selling.

Thames Valley Police has reminded residents that all legitimate door-to-door tradesmen should be equipped with genuine certificates which are issued by the force.
