yeah, that'll be their punters. but the women say they're here voluntarily, meaning officers have no choice but to leave them here. this is happening in every corner of the country. sex trafficking is rife in the uk. i don't think we've got anywhere near the true picture of how many victims there are there. we don't know where to go to, we don't know where to visit. the houses, it'sjust a normal house in a normal street. people will have neighbours who are victims of sex trafficking. getting the women on side is colin's best chance of catching the traffickers. hey, you ok? we're police officers. but it rarely works. cases hardly ever make it to court. it's ok, it's ok, don't worry, don't be scared. the girls�* distrust of police starts long before they reach the uk. back in romania, we found sometimes, when they disappear, police don't investigate.
