This is definitely a targeted operation and the detective's comments in no way make punting with UK indies a risk in Swindon:
"The intelligence identified that a number of women were advertising themselves as sex workers on various websites. Further research identified a link between the profiles being created and suspects who appeared to be involved in setting up the profiles and in the transportation of the women into the UK. All the people involved hail from Romania."
Maybe now there will be fewer EE profiles from Romanian pimps in Wiltshire. As the police in the SW work regionally for some crimes, there's a fair chance of the same action in other areas.
