How to recognize a victim?

Human trafficking is often hidden behind legal activities, and therefore difficult to detect. However, there are ways in which it can be done, and there are also clear indicators of this criminal act, which suggest that a person has absolutely no control over their life and destiny. Victims are controlled or intimidated, monitored or accompanied by someone, not allowed to speak for themselves, they have no identity documents,are not familiar with the neighbourhood they live/work in, have injuries/bruises from beating and/or weapons, show visible signs of torture, cigarette burns, cuts, show signs of malnutrition, express fear and intimidation through facial expressions and/or body language.
