A father and son working as bail bondsmen in Covington and Amite were arrested Friday in a human trafficking investigation led by Louisiana State Police and the FBI.

James E. Johnson Jr., 53, of Bush, is accused of soliciting sexual favors from multiple victims in exchange for bond debt relief. He was arrested Friday morning without incident at his office in Covington and was booked into the St. Tammany Parish Jail on two counts of human trafficking, two counts of first-degree rape and a count of sexual battery.

Detectives also seized 27 firearms from Johnson's residence and business offices, according to a State Police news release.

Johnson's son and business partner, Patrick Johnson, 31, was also arrested after detectives discovered pornography involving juveniles during a search of the pair's office in Amite. 

Patrick Johnson was booked into the Amite Jail on three counts of possession of pornography involving juveniles. 

The investigation is ongoing, with officials believing there may be unreported victims. Additional arrests and charges may be forthcoming, officials said.
