Law Enforcement (Powers and Responsibilities) Act 2002

A police officer may give a direction under this Part to persons comprising a group.

In any such case, the police officer is not required to repeat the direction (or the warning referred to in section 198(6) in the case of a direction given under section 198), or to repeat the information and warning referred to in Part 15, to each person in the group.

However, just because the police officer is not required to repeat any such direction, information or warning does not in itself give rise to any presumption that each person in the group has received the direction, information or warning.
