SAN ANTONIO -

While executing warrants for drugs and prostitution, San Antonio police detectives uncovered an elaborate human trafficking operation at two homes on the city's east side.

"The house was also set up with homemade walls, hidden rooms and setups which allowed activity in the room to be covertly observed,” said San Antonio police Chief William McManus.

Glen Dukes, 43, is charged with two counts of trafficking of persons and one parole violation.

Investigators say he had at least two known victims that he prostituted and he physically assaulted those victims to make them comply.

"The setup was sinister in my words,” McManus added.

SAPD patrol officers alerted detectives that various types of criminal activity took place inside homes. Police believe crimes in addition to drugs and prostitution might have been perpetrated at the homes.

Neighbors told KSAT 12 News that both locations are well-known for prostitution.

Dukes, who has a lengthy criminal history, had at least two victims that he used as prostitutes," said McManus.

But police believe there may be more.

Dukes drives a green Chevy Suburban with Texas license plate number AY2-6990. The vehicle is in police custody, but SAPD released the description hoping that someone might have seen the vehicle and could give police more information on the case.
