A 16-year-old girl was picked up outside her school, then drugged and forced to have sex with 16 men in a week, according to police.

Seven men, two of who are father and son, have been arrested on charges of sexual battery.

They were identified as Cornelius Edwards, Mark Evans, Jerome Grace, Greg Hill, Derrick Powell, Derrick Powell Jr, and Branden Sands, reports WPLGLocal.

She was reported missing by her school on 4 December after reportedly getting into a car with three other people. It is not known if she knew any of the people in the car.

According to authorities, she was then taken to several locations in north-eastern Miami-Dade county, where she was given marijuana and cocaine, and made to have sex with more than 16 men over the course of a week. She was given a quota of $1,200 to make over the course of the week.

She was forced to have vaginal, oral and anal sex, and on two occasions, she was forced to have sex with more than eight men at once, police allege.

"Every time you think you have seen the worst of the worst, a case like this pops up," State Attorney Katherine Fernandez Rundle told NBC Miami. "It's nauseating. It's horrifying and unspeakable. How human beings could be so barbaric to each other is a mystery to me."

Authorities said the girl is now safe.

"She's in a safe place right now," Miami-Dade County state attorney Katherine Fernandez Rundle said. "Hopefully we'll learn more and see where we go with this case."

All seven men are being held without bond.

The State Attorney's Office said the investigation is ongoing.
