“If through no fault of his own a person gets mixed up in the tortious acts of others so as to facilitate their wrong-doing he may incur no personal liability but he comes under a duty to assist the person who has been wronged by giving him full information and disclosing the identity of the wrongdoers. Justice requires that he should co-operate in righting the wrong if he unwittingly facilitated its perpetration. This is the principle recognized by the House of Lords in Norwich Pharmacal Co v Customs and Excise Commissioners [1974] AC 133.”
