Is the upcoming auto show a concern for Homeland Security? Authorities are warning about human trafficking.
Human trafficking equates to prostitution, including underaged victims, according to federal officials.
Human trafficking arrests have been made during recent auto shows, and other large events that attract thousands of visitors.
A multi-agency investigation uncovered a trafficking operation in 2017, when they say 15 teen and adult victims were saved.
Undercover agents made 22 arrests last year at motels and hotels.
