PHILADELPHIA (CBS) – A Philadelphia man has been charged with child pornography and the sex trafficking of children.

Enoch Smith, a 35-year-old also known as “Drees” or “Idris,” allegedly operated a prostitution venture in Philadelphia and recruited young girls to work as prostitutes. He also posted advertisements on the internet that advertised the girls either scantily clad or topless with their hands covering their breasts, the price and a phone number to call to arrange a meeting with them.

In an indictment, the United States Attorney, Eastern District says that at least one girl was under the age of 18.
