Police arrested a South Florida preacher for allegedly having sexual relations with a teenager.

34-year-old Junior Augustin was allegedly having sexual relations with a 16-year-old girl who was the daughter of the pastor at a church where Augustin preaches.

The victim’s sister told officials that before the alleged sexual assault happened, the victim’s family and Augustin’s family were extremely close.

Investigators say the teen girl took care of Augustin’s young children in his Deerfield Beach home soon after his wife had their youngest child. The 34-year-old is the father of eight children.

Augustin faces charges of sexual assault and performing a lewd and lascivious act, and he remains at the Broward County Jail in Fort Lauderdale on a $100,000 bond.
