A man and woman from Memphis, Tenn., are jailed in Harrison County, Miss., on human trafficking, prostitution and drug charges.

Bond for both 24-year-old Eric Allen Underwood and 27-year-old Dominique Yvonne Watkins was set at $200,000 on the human trafficking charge. The Harrison County Detention Center's inmate tracking website shows total bonds of $302,085 for Underwood and $227,675 for Watkins.

It was not clear Sunday if they had attorneys.

Biloxi police Sgt. Aldon Helmert tells The Sun Herald both were arrested Saturday after an undercover investigation of escort websites. He says the investigation took less than a day.

This is the second such case investigated by Biloxi police since Sept. 30.

Police won't release additional information, saying the investigation continues.
