In terms of the type of data being acquired, Figures 11 and 12 show, generally speaking, an
even split between the acquisition of traffic and subscriber information, and that the majority
(75%) related to telephony. This is broadly similar to that reported in previous years by
IOCCO, although the proportion of items relating to the internet is steadily increasing.

Figure 13 shows that, similar to previous years, the data acquired largely relates to suspects,
their associates or vulnerable persons (typically where police are trying to locate them for
their safety).
