“The information acted on by the arresting officer need not be bases on his own observations, as he is entitled to form a suspicion based on what he has been told. His reasonable suspicion may be based on information which has been given to him anonymously or it may be based on information, perhaps in the course of an emergency, which turns out later to be wrong. As it is the information which is in his mind alone which is relevant however, it is not necessary to go on to prove what was known to his informant or that any facts on which he based his suspicion were in fact true. The question whether it provided reasonable grounds for the suspicion depends on the source of his information and its context, seen in the light of the whole surrounding circumstances.”

The judgment at paragraphs 67 and 68 provides support for the view that • entering into or becoming concerned in an arrangement involves an act done at a particular point in time, and • a person does not enter into or become concerned in an arrangement under S.328 and no offence under this section is committed until such an arrangement is made, and • no preparatory or intermediate step taken in the course of transactional work which does not itself involve the acquisition, retention, use or control of property will constitute the making of an arrangement under S.328. 3.4 Where a solicitor engaged on transactional work forms a relevant suspicion, he will have to consider 3.4.1 whether an arrangement within the terms of S.328 exists and, if so, whether he has entered into or become concerned in that arrangement or may do so at some point in the future; 3.4.2 if there is no existing arrangement under S.328, whether an arrangement within the terms of S.328 will or may come into existence at some date in the future. 3.5 The word “arrangement” is not defined in Part 7 of POCA, but under S.328 it is an arrangement which [the alleged offender] “knows or suspects facilitates (by whatever means) the acquisition, retention, use or control of criminal property....”
